technology have been critical facilitators of the high-rise structures that define
our urban skylines. However, upgrades in elevator safety, robustness, quality,
space efficiency, and performance are needed to support infrastructure development
and meet societal needs.</b> <b><span style="mso-bidi-font-family: Arial;">Here
John Mitchell, <span style="mso-spacerun: yes;"> </span>global sales and
marketing director at <a href="https://www.cpaltd.net/drives.html?utm_source=Stone%20Junction&utm_medium=blog&utm_campaign=CPA218">elevator
<span style="mso-spacerun: yes;"> </span>power solution specialist,</a> CP
Automation explains the importance of opting for the right surge protection
device (SPD) to reduce unnecessary downtime.</span></b><p></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">Elevator modernisation can feel like an expensive
and time-consuming undertaking. Before embarking on a modernisation project, a
thorough survey is undertaken to assess the current performance of the system. Once
armed with this information, an assessment of whether a modernisation is necessary
and, crucially, whether it makes business sense can begin.</span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">One of the most important considerations
should of course be the safety of the passengers, maintenance personnel and the
lift system. <span class="hscoswrapper">A more modern, safer elevator that
complies with the latest standards and offers improved reliability is clearly the
desired outcome. However, an important safety consideration, that is often
overlooked, is the effectiveness of the system’s SPD.</span></span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><b><span style="mso-bidi-font-family: Arial;">Reducing downtime and maintenance costs</span></b></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">Elevators typically have service lives of
over 20 years, but during this time their performance can decline, leading to increased
maintenance costs, increased energy usage and the risk of downtime.</span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">Modernisation can make elevators more
energy-efficient and reduce energy costs by feeding otherwise wasted energy
back into the building whenever the elevator is travelling in an out of balance
direction, rather than releasing it in the form of heat through braking
resistors. </span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">For example, CP Automation’s Magnetek range
of elevator products include drives with in-built regenerative technology and also
separate regenerative ‘bolt-on’ modules that can be retro-fitted to any
existing AC drive to produce substantial energy savings — savings which can be
easily calculated using our online Energy Savings Calculator tool. <span style="mso-spacerun: yes;"> </span><span style="mso-spacerun: yes;"> </span></span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">However, as the hardware and software used
in elevator applications has advanced, this has brought about an entirely new
set of problems and maintenance considerations. While this hardware and
software is more reliable than ever before, it is also highly sensitive to
fluctuations in power surges.</span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;">High voltage
surges are normally covered by surge protectors. However, traditional SPDs do
not account for <span style="mso-bidi-font-style: italic;">low level</span>
transient surges <span style="mso-bidi-font-family: Arial;">that can occur
countless times a day, exaggerated by VSD usage</span>. Don’t let the name fool
you — these transient surges in the sine wave are very damaging to electrical
equipment, as the additional peaks and troughs in the sine wave cause confusion
to sensitive devices and machines. </p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">This can cause recurring random failures,
lockups and deprogramming, such as those experienced by human machine
interfaces (HMIs) used in Destination Despatch systems on each floor. So, to
protect </span>the electrical control system, the VSD and lift controller from
transients, a more sophisticated <span style="line-height: 200%; mso-bidi-font-size: 10.0pt;">transient protection system is needed.</span><span style="mso-bidi-font-family: Arial;"> Downtime and maintenance can be eliminated
if the right surge protection such as <a href="https://www.cpaltd.net/sinetamer-downloads">SineTamer</a> is in place.</span><span style="line-height: 200%; mso-bidi-font-size: 10.0pt;"> </span><span style="mso-bidi-font-family: Arial;"></span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="line-height: 200%; mso-bidi-font-size: 10.0pt;">Crucially, SineTamer’s
frequency attenuation network monitors the frequency, not just the voltage. </span>The
engineered transient disturbance filter is designed to monitor all 360 degrees
of the sine wave, making it capable of detecting rapid changes in frequency.
This vigilance in turn prevents issues caused by false zero crossings of the
sine wave.<span style="line-height: 200%; mso-bidi-font-size: 10.0pt;"></span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">When approached carefully, modernisation — whether
that’s partial or a complete replacement — can lower repair costs, reduce
faults and increase energy savings while improving comfort, efficiency, safety
and aesthetics. However, it’s important that facilities’ managers do not
overlook the importance of protecting this sensitive equipment from harmful
power surges.</span></p>

Environment in Low-Voltage (1000 V and Less) AC Power Circuits C62.41.1-2002, utility
capacitor bank switching transients is an issue that exists in nearly every
electrical system. Here, John Mitchell, global sales & marketing director
at </span></b><span style="mso-bidi-font-family: Arial;"><a href="http://bit.ly/36Tu2wp"><b>supply, installation and repair specialist</b></a><b>
CP Automation, offers an accessible introduction to this topic, and <span style="mso-spacerun: yes;"> </span>details why effective surge protection is the
answer.</b> </span>
</p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">The application of utility capacitor banks
has long been accepted as a necessary step in the efficient design of utility
power systems. Generally, capacitor switching is considered a normal operation
for a utility system and the transients associated with these operations, are largely
not a problem for utility equipment. </span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">However, this is not always the case. </span>High
voltage surges are normally covered by surge protectors. In contrast, traditional
surge protection devices (SPDs) do not account for <span style="mso-bidi-font-style: italic;">low level</span> transient surges.<span style="mso-bidi-font-family: Arial;"> These low level transient surges can be magnified in a customer
facility, if the customer has low voltage power-factor correction capacitors, or
can result in the nuisance tripping of power electronics-based devices, such as
variable speed drives (VSDs), which are very susceptible to changes in power
quality.</span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">There are a number of transient-related
concerns that are generally evaluated when transmission and distribution shunt
capacitor banks are applied to the power system. One example of these many
switching events that can cause transients on a utility system, is capacitor
energising. Due to their regularity and impact on power system equipment, they often
receive special attention.</span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">Another example is distribution system
overvoltages, resulting from the energisation of transmission system capacitor
banks. These can be sufficient to spark over gapped SPDs — typically <span class="acopre">silicon-carbide</span> (SiC) design. In comparison, gapless SPDs —
typically <span class="acopre">metal oxide</span> (MOV) design, should be capable
of withstanding this event. </span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">These transient switching overvoltages might
simply damage low-energy SPDs or cause a nuisance trip of power
electronics-based equipment. Nevertheless, case histories have been reported of
complete failure of end-user equipment. </span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">Other power quality symptoms related to
utility capacitor switching include:<b> </b>customer equipment damage or
failure, tripping of process equipment, SPD failure, and computer network
problems — all of which are highly disruptive. </span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">Similarly, capacitor switch restrike events
can produce high-voltage surges that result in severe energy-duty for adjacent SPDs,
or damage to unprotected equipment. It is therefore recommended to select a
switching device that will minimise the possibility of a restrike event. In
addition, it is advisable to protect adjacent equipment with SPDs of
appropriate size.</span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><b><span style="mso-bidi-font-family: Arial;">Further application concerns often include: </span></b></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">• Overvoltages associated with normal
capacitor energising </span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">• Open line/cable end transient overvoltages
</span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">• Phase-to-phase transients at transformer
terminations </span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">• Voltage magnification at lower voltage
capacitor banks </span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">• Arrester duties during restrike events </span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">• Current-limiting reactor requirements </span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">• System frequency response and harmonic
injection </span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">• Impact on sensitive power electronics
loads at customer facilities </span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">• Ferroresonance and dynamic overvoltage
conditions </span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">While power quality issues can be caused by
an unexpected event such as a lightning strike to the grid, issues relating to the
threat of lower level transient surges can be and <i>should be</i> mitigated
against.</span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">To eliminate the effects of low-level
switching transient events, transient protection systems such as SineTamer
offer a new opportunity to protect valuable assets from the transient events
that occur millions of times, every day. Its frequency attenuation network
monitors the frequency, not just the voltage. The engineered transient disturbance
filter is designed to monitor all 360 degrees of the sine wave, making it
capable of detecting rapid changes in frequency.</span></p>
<p class="MsoNormal" style="line-height: 200%; text-align: justify;"><span style="mso-bidi-font-family: Arial;">Although this article is certainly not
intending to be a comprehensive review of this topic, it provides strong
evidence for the need to protect equipment from low level transient surges.
Choosing the right SPD is therefore a crucial step and shouldn’t be ignored.</span></p>

<b>According to
the </b><a href="https://www.carbontrust.com/es/node/182"><b>Carbon Trust</b></a><b>,
cash savings of up to 20 per cent can be achieved through energy efficiency
measures such as installing variable-speed drives (VSD) for fans, pumps, and
other motor driven systems. But, a one size fits all approach to energy savings
just won’t do. </b><b><span style="line-height: 200%; mso-bidi-font-size: 10.0pt;">Here,

<div class="MsoNormal" style="line-height: 200%; text-align: justify;">

50001 standard</span></a><span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;"> requires organisations to establish,
implement, maintain and improve an energy management system. To make energy
savings, a plant manager must first understand their facility’s energy usage.
It sounds obvious, but in reality, achieving energy control and crucial ongoing
energy savings requires a strategized approach. The first step is to measure
your energy usage. </span></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">Many
modern distribution and energy management systems already incorporate energy
monitoring and logging facilities. However, they may only have a limited amount
of memory and are unable to store results over an extended period. In addition,
many integrated monitors only store summarised data that do not provide the
level of detail needed for effective energy optimisation.</span></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">Portable
power and energy loggers (PELs) provide a convenient and cost-effective alternative,
with far superior capabilities. These PELs, from Chauvin Arnoux for example,
can be installed in several different locations, with data from different
processes or equipment available on a single screen. A real benefit of these
modern devices is that equipment doesn’t need to be turned off and isolated
during the installation process. </span></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">The
next step is carrying out an energy audit. The data from the PEL will show
where the most energy is being used in your plant and consequently where the
most potential for energy savings can be found. The results from this report
will inform the type of improvements to implement and crucially where they
should be implemented.</span></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">

<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">Energy
saving opportunities can fall into two broad categories, those that relate to
the workplace environment and technical aspects of the electricity supply. For
example, a plant could improve the efficiency of the workplace environment by cutting
down on unnecessary out-of-hours usage by switching to LED lighting </span>with
occupancy sensors. On the other hand, an energy audit may find that a motor is
consuming a high amount of wattless or useless power. In this instance, power
factor correction would need to be installed to reduce this wastage, without
compromising the performance of the equipment.<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;"></span></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">It’s
one thing implementing energy savings, but it’s also important to continually
monitor your system to ensure you’re getting ongoing energy improvements.
Plants should also formulate a metering plan to measure and analyse energy
usage over an extended period of time. This will assess whether the chosen
energy efficiency measures have been effective or whether further improvements
can be made. </span></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">Plants
may choose to implement energy efficiency schemes for a range of reasons. While
there are several universal energy saving fixes, it’s important that facilities
use a targeted approach, which accurately monitors their systems to achieve the
most effective energy and cost saving potential.</span></div>

<span style="mso-bidi-font-family: Arial; mso-bidi-font-weight: bold;">Transients, interruptions,
harmonics, swells, dips, sags and unbalance. These are just some of the power
quality problems that can have devastating effects for industrial businesses. Power
quality d</span><span style="background: white; color: #262626;">eviations may originate within the source of supply, load
equipment or from interactions between the source and the load. </span></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">

<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">While
utilities are finding ways to decrease the number of outages and restore power quickly
by improving the reliability and resilience of the grid, what can businesses do
to safeguard their operations? Effective power system protection and power quality
monitoring can take different forms but should protect your business from
downtime, data loss and equipment damage.</span></div>

<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">Downtime
can lead to production loss, which is financially disabling for any business,
especially in an industrial environment where businesses are under pressure to
increase the efficiency of their operations. Preventing downtime should therefore
be a priority for businesses of all sizes. Power outages are a major cause of
downtime and, unfortunately, they’re on the rise. Businesses can however take
steps to diminish the impact of power outages, by installing an uninterruptible
power supply (UPS). </span></div>

<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="color: black; mso-bidi-font-family: Arial;">A UPS is designed to provide a secondary
or backup power in the event of loss of utility power. </span><span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">The
first step in implementing a new UPS system, is establishing whether a facility
requires </span>a single- or 3-phase UPS. Generally, loads of 20kVA or less can
safely use a single-phase UPS, whereas larger loads will likely need a 3-phase
UPS. The rating of the UPS will be determined by the type of supply, the load
being drawn by the system (kVa value) and the supply voltage.<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;"> </span></div>

<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">Data
is a powerful business tool, so preventing data loss should be high on every
business’s agenda. Data loss can happen due to human error, hardware
malfunctions and also through power failure. There are a few things your business
can do to manage this scenario. Firstly, make sure that offsite data backups
are available. Secondly, invest in a reliable surge protection device (SPD) and
a UPS system. This may prove valuable in preventing a forced shutdown, providing
valuable additional minutes to retrieve data.</span></div>

<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt;">There’s more to power
protection than preventing power outages. The sine wave has remained the same
since the late 1800s, however the sensitivity of the equipment that is
connected to the grid has dramatically increased. Transient surges and harmonic
distortion are two common power quality issues. </span></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt;">A basic SPD and a variable
frequency drive (VFD) may be used in conjunction to mitigate the damaging
impact of high-power surges. However, even with basic surge protection, many facilities
are still faced with some machine breakdowns due to low level switching transient
events.</span></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
Transient surges
are a brief change in voltage frequency that occur thousands of times a day but
are very damaging to electrical equipment. The additional peaks and troughs in
the sine wave caused by transients results in confusion to sensitive devices such
as industrial computers, or CNC machines. Some facilities may believe that
built-in surge protection adequately protects their equipment, however the built-in
protection is not doing enough to protect valuable systems and prevent false zero
crossings caused by transients. </div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">Consider
this as an example. </span>High power electrical devices such as elevators and
air conditioning systems or components like compressors and motors, require
large amounts of energy to turn on and off. This switching creates a sudden and
short demand for power, which can deviate from the normal voltage flow in the
electrical system. If adequate protection is not in place, over time this can
lead to premature wear of components and in severe cases, can lead to immediate
component failure. </div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">Similarly,
the damage caused by </span>harmonics can seriously impact equipment service life.
The thermal stress on components can cause excessive wear and premature failure.
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">The rise of non-linear loads in industrial environments has resulted in
the growing problem of harmonic currents. The </span>most common symptoms include
voltage notching, motor vibration, arcing on bearings, nuisance tripping,
electromagnetic interference (EMI/RFI) and overheating. </div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="background: yellow; mso-bidi-font-family: Arial; mso-highlight: yellow;"><br /></span></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="mso-bidi-font-family: Arial;">So, how can this be combated? Harmonic </span>filters
monitor the network and inject the necessary amount of compensation current at
any given time, which restores current waveform and lowers current consumption.
This makes the devices ideal for installations in which current load changes
constantly, such as in IT applications and data centres.</div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<b><span style="line-height: 200%; mso-bidi-font-size: 10.0pt;">What next?</span></b></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="mso-bidi-font-family: Arial;">Due to rapid advancements in equipment, varied
approaches to the identification and mitigation of power quality issues have arisen.
This has led to some facilities using setups which are outdated and no longer fit
for purpose. </span></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
So, how do you
decide which power quality products you need? Performing a site audit is a good
place to start. This will identify the power quality problems that are plaguing
your facility, so that you can choose the right surge protectors, harmonic
filters and power quality analysers to mitigate damage. <span style="mso-bidi-font-family: Arial;"></span></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
Whether facility
managers choose to completely update their power protection devices, or enhance
what they already have, monitoring the electrical characteristics in your
facility can result in less downtime, limit data loss and protect valuable
equipment from damage. </div>

<b>Batman and Robin, Mario and
Luigi, Wallace and Gromit. In film, the role of the sidekick is crucial in aiding
the protagonist to achieve their overall goal. In the fight against power outages we</b><b> explain the necessity of protecting uninterruptable
power supply (UPS) systems with a surge protection device (SPD) that accounts
for transient surges. <o:p></o:p></b></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
The role of a UPS is to provide
a secondary or backup power in the event of loss of utility power. The UPS protects
electrical and electronic systems, process controllers and data against the loss
of the primary power source.<br />
<!--[if !supportLineBreakNewLine]--><br />
<!--[endif]--><b><o:p></o:p></b></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
A common misconception is that
SPDs are unnecessary due to the built-in protection already provided by UPS
systems themselves. The downside of this "built in" suppression is that
the typical UPS, if subjected to a line to ground transient, may allow a significant
amount of the transient downstream to the loads. <o:p></o:p></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
Transient protection should
exist at the input to all electronic loads and the UPS is no exception. This is
where SPDs come in, to prevent excess
voltage appearing at the terminals of sensitive equipment.<b> </b>Integrating one of
these devices into a systems architecture, ensures the life of the UPS and importantly
any equipment to which the UPS is supplying power.<o:p></o:p></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
High voltage
surges are normally covered by surge protectors. However, traditional SPDs do not
account for low level transient
surges. These transient surges in the sine wave are very damaging to electrical
equipment, as the additional peaks and troughs in the sine wave cause confusion
to sensitive devices and machines downstream. Transient surges can lead to false
zero crossings of the sine wave — the instantaneous point at which there is no
voltage present.<o:p></o:p></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
During maintenance and downtime
on the UPS, the SPD will filter out the transients and surges from the line
during the static by-pass mode or maintenance by-pass mode of operation, protecting
the connected computer equipment from damage. <o:p></o:p></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
However, not all SPD technology is the same.
The SineTamer cascade system for example, offers much more than a standard surge
protection device. It is an engineered transient disturbance filter, designed
to monitor all 360 degrees of the sine wave. Using 360-degree monitoring, the device
can prevent issues caused by false zero crossings of the sine wave.<o:p></o:p></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
If an organisation has already committed
to investing in sophisticated computer equipment and a UPS unit to protect against
power outages, the investment in an SPD is minimal by comparison and a very
natural progression. The benefits of this additional protection can be significant,
resulting in fewer maintenance problems and less downtime, which can reap havoc
for businesses. <o:p></o:p></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
While a UPS may function on its own,
the SPD is a reliable and necessary sidekick, providing complementary functions
in the fight against power failure problems. <o:p></o:p></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div align="center" class="MsoNormal" style="line-height: 200%; text-align: center;">
</div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">

between SPD technology can be key to protecting your devices. For more information about CP Automation’s SineTamer

We have introduced the new Comsys ADF P25 small compact active filter to our supply range. This ultra-compact filter addresses recurring power quality issues in industry for applications where space is at a premium.<br />
<br />
Power quality is a growing concern for utility providers, manufacturers and data centres. The more advanced technology in today’s facilities is putting higher demand on the electrical grid, making machinery particularly susceptible to power quality issues and unexplained equipment malfunctions and stoppages.<br />
<br />
This coincides with the dwindling space in today’s facilities — there often isn’t room for a bulky power filter. Improved space optimisation for this equipment enables higher production volumes in the same footprint, saving business huge sums of money in floorspace.<br />
<br />
“We have taken 20 years of know-how in high power active harmonic filters and built the most robust small size active harmonic filter on the market,” explained Rickard Jacobson of Comsys.<br />
<br />
The Comsys ADF P25 addresses the need for an ultra-compact power filter, without compromising on protection. It filters a variety of electrical disturbances, including transients and harmonics, which could go on to cause overheated transformers, nuisance tripping and non-compliance with grid codes.<br />
<br />
“Our customers are attempting to maximise on every inch of floor space,” explained John Mitchell of CP Automation. “At the same time, they are also optimising energy efficiency and proactively protecting machinery from unnecessary downtime. Luckily for them, the ADF P25 offers the same performance as its big brothers, the ADF P300 or ADF P100, but in a much smaller size.<br />
<br />
“The filter is suitable for new build facilities or as part of a retrofit approach and it is compatible with all three-phase low voltage applications. To get the filter commissioned, all that is needed is a laptop with an ethernet port and recent web browser. Investing in this is a no-brainer to save on footprint, downtime and parts replacement costs.”<br />
<br />
The ADF P25, as with the other Comsys products that CP Automation supplies, are engineered and manufactured in Sweden to extremely high standards. The expert engineering has enabled several ADF P25s to be combined, offering modular and scalable design as facilities increase power demands.<br />

<a href="https://www.cpaltd.net/">Industrial sales and repair specialist,</a> CP Automation, has introduced the Re Spa web guiding (WG) series to its product portfolio. These intelligent retrofit parts are set to solve common problems for tissue, aluminium foil, paper and plastic film manufacturing and processing plants, by offering precise alignment of web winding and consistent printing and cutting processes. <script src="http://s7.addthis.com/js/250/addthis_widget.js#pub=xa-4ae9cd543501b935" type="text/javascript"></script><br />
<br />
Effective alignment from the unwinder to the rewinder is a must for any converting businesses wanting to increase productivity and product quality. Re Spa’s web guiding systems are an ideal retrofit option that can be added directly to the existing system’s unwinder, to guarantee a fast and accurate correction of material position.<br />
<br />
The Re Spa <a href="https://www.cpaltd.net/re-spa-wg-705-pivoting-compact-web-guiding-system-wg-705-400-350-dx-sx.html">WG705</a> web guiding product is designed for reels up to 600mm in width, while the WG2003 suited to reels larger than 600mm. Both are fitted with ultrasonic sensors that feedback the position of the material to the web guiding controller, which sends a correction signal to the roller to reposition the material accordingly.<br />
<br />
A further source of frustration for converting is the alignment of the web prior to folding after the cutting process has taken place. At this point, the web is smaller, so there is less room for error. The material must therefore be perfectly aligned on the roller in order to create precisely central folds. The WG705 offers easy pre-folding alignment correction, guaranteeing a precise fold in the middle of the product.<br />
<br />
“Re Spa has identified a clear need for this product in the converting industry,” explained Tony Young, director of CP Automation. “Factories in all industries are becoming smarter, and tissue, film and foil processing and manufacture certainly won’t get left behind. Alignment issues don’t need to be a costly or recurring problem anymore, as these devices from Re Spa are now available for post-unwinding and post-cutting precision.<br />
<br />
“Businesses that have retrofitted these parts are already reducing their production waste, reducing time spent on setup and increasing print quality.”<br />

There are over 900,000 elevators in operation in the US alone, many of which experience mind-boggling lock ups and loss of programming. John Mitchell, global sales & marketing director at supply, installation and repair specialist CP Automation, explains how elevator maintenance managers can prevent these annoying occurrences. <script src="http://s7.addthis.com/js/250/addthis_widget.js#pub=xa-4ae9cd543501b935" type="text/javascript"></script><br />
<br />
On average, 20,000 people are carried by each of these elevators every year. That equates to 18 billion trips made by elevator annually, just in North America. Elevators play a crucial role in human logistics and thus present a lucrative opportunity to improve the efficiency of buildings worldwide.<br />
<br />
Modern buildings are being erected to greater heights than ever before. As a result, newly implemented elevators are required to travel higher and faster than their predecessors. With these changes come a new set of problems and maintenance issues for engineers.<br />
<br />
To manage these new heights, today’s elevator software and hardware are more complex, and therefore more sensitive to fluctuations in power surges. This does not only refer to the strong surges from lightning strikes or utility companies, but also the transient surges that can happen thousands of times a day.<br />
<br />
Transient surges are a change in fundamental frequency of power that can occur multiple times a day on the power supply network. These surges are a result of switching operations of inductive loads, such as air-conditioning units, transformers and lift motors.<br />
<br />
Surges related to lift motors are most commonly linked with elevator power quality issues. If the lift motor is controlled by a variable frequency drive (VFD), the business may benefit from increased efficiency and reduced energy costs. However, this does not manage the low-level transient surges that can occur countless times a day, exaggerated by VFD usage.<br />
<br />
Transient surges can lead to false zero crossings of the sine wave — the instantaneous point at which there is no voltage present. In a sine wave, this normally occurs twice during each cycle. Devices can be falsely triggered because of fast changing signals caused by transients, as they believe the zero point has been crossed, even when it hasn’t. It can cause confusion for all equipment on the grid.<br />
<br />
Whether it is caused by transients or a freak utility power surge, insufficient power quality is destroying many elevators and their related equipment. For elevator operation, this can cause recurring random failures, lockups and deprogramming of human machine interfaces (HMIs) on each floor. However, this downtime and maintenance can be eliminated if the right protection is in place.<br />
<br />
Typical surge protection devices are unable to prevent these issues as they are voltage triggered only. This means built in surge protection systems are not a feasible option. The answer to this problem is using a SineTamer® cascade system.<br />
<br />
This system offers much more than a standard surge protection device. It is an engineered transient disturbance filter, designed to monitor all 360 degrees of the sine wave. Using 360-degree monitoring, the SineTamer® can prevent issues caused by false zero crossings of the sine wave.<br />
<br />
Results from the field<br />
In Central America, one business was faced with a major utility generated power surge, destroying several elevators and related equipment in its facility. Yet, right next door, being fed from the same transformer, not a single elevator component was damaged. When investigated, the foreman of the unaffected building explained they had installed SineTamer®.<br />
<br />
Over in South America, the Montevideo World Trade Centre contained 30 elevator systems, routinely experiencing 5-7 issues daily. In addition to those were the constant deprogramming failure of HMI’s on each of the 22 floors. Upon installation of the SineTamer®, all failures, lockups and loss of programming ceased by 100 per cent.<br />
<br />
The US boasts huge numbers of elevators in operation today, and interestingly around 914,000 new are sold across the world each year. As worldwide construction of tall buildings continues to increase, improving management of transient surges will mean that new and old elevators will now have a fairer chance in lasting the test of time — without costly maintenance issues.<br />

<b><br /></b>
<b><br /></b>
<b>Whether a data centre is onshore or offshore, the universal electrical issue that affects them all is harmonics. Here, John Mitchell, global business development manager of <a href="https://www.cpaltd.net/?utm_source=StoneJunction_CPA163&utm_medium=PR">supply, repair and field service specialist</a> CP Automation explains the most effective way to mitigate harmful harmonics in a data centre. </b><br />
<br />
Associated with alternating current (AC) power lines, harmonics can infiltrate both the voltage and current of electricity. This results in costly and disruptive damage to the electrical distribution systems found in data centres and many other facilities. Let’s delve deeper into the issue.<br />
<br />
For the best efficiency and performance in a data centre, the goal is to have voltage and current waveforms primarily consisting of the fundamental frequency, with minimal higher-order frequencies. Most utilities provide power with a reasonably smooth waveform, however, non-linear loads such as servers, variable frequency drives (VFDs) and other electrical devices can distort current and voltage waveforms.<br />
<br />
These distortions are known as harmonics. These changes appear as supplemental frequencies higher than the fundamental frequency, which is 60 Hz in the U.S. and 50Hz in most other countries.<br />
<br />
Harmonic currents are often exaggerated by the power supply units (PSUs) within the IT equipment itself, or by VFDs in cooling and ventilation equipment. Harmonic currents can then distort the voltage that is consumed by IT equipment, as the devices pull current distortion through an impedance.<br />
<br />
<b>Why harmonics matter</b><br />
Minimising energy costs and maximising reliability are top priorities for most data centre operators, but harmonics make both these goals harder to achieve.<br />
<br />
Arguably the most prolific concern about harmonics is the increased losses on the power system conductors and transformers, adding heat to the power chain that drives up power and cooling costs. This has a knock-on effect on capital expenses, as harmonics reduce the lifespan of electrical equipment. Because of this, businesses may need to purchase replacement devices prematurely.<br />
<br />
Harmonics can also result in costly utility penalties, as energy companies must compensate for harmonic-related waste by deploying additional generating capacity. For this reason, and to discourage harmonic pollution, many utility providers penalise customers that exceed distortion limits as defined by the IEEE-519 standard.<br />
<br />
While these power quality issues are generally understood in the technical community, less appreciated is the effect of harmonic currents on the overall efficiency of a data centre. Ultimately, harmonic currents are wasted energy that appear as heat. This means the amount of heat that must be removed from the data centre is increased — a common and highly-publicised issue for data centres.<br />
<br />
<b>The answer</b><br />
While there are a range of options for mitigating harmonics, the right option depends on the data centre in question, the facility’s budget and the loads it supports. CP Automation recently helped one customer that was upgrading the cloud-based servers in a data centre in Middlesex, UK. By assessing the data centre facility and evaluating the current power quality issues, the audit identified any issues that could arise from the upgrade.<br />
<br />
After this assessment, it was clear the best option for this facility was an active filter. CP Automation then supplied and installed a <a href="https://www.cpaltd.net/media/downloads/Comsys-ADF-P300.pdf">Comsys ADF P300 active dynamic filter</a> to alleviate any potential issues associated with harmonics.<br />
<br />
Active harmonic filters are the most flexible solution on the market. They monitor the network and inject the necessary amount of compensation current at any given time, which restores current waveform and lowers current consumption. This makes them ideal for installations for applications in which current load changes constantly, as was the case with the data centre in Middlesex.<br />
<br />

Line harmonics continue to be a costly issue for data centres, but fortunately, IT and facilities managers have access to a wide array of harmonic-mitigation technologies. If you’d like to discuss your own needs for harmonic filtering, contact the CP Automation team on +44 (0)1724 851 515.</div>

Industrial repair specialist <a href="https://www.cpaltd.net/">CP Automation</a>, has partnered with SineTamer to distribute surge and transient protection systems across Europe, the Middle East and Asia. The alliance will help manufacturers to decrease downtime caused by standard surge protection devices by mitigating transient surges caused by variable frequency drives (VFDs).<br />
<br />
Transient surges are a change in fundamental frequency that occur thousands of times a day when using a VFD. Standard surge protection devices are voltage triggered only and do not account for these transient surges that can lead to confusion in electrical systems. Examples include false zero crossing, false triggering of diodes and timing issues.<br />
<br />
“The SineTamer transient protection system will be the saving grace for many facilities managers,” explained John Mitchell, global business development manager at CP Automation. “The sine wave has actually remained the same since the late 1800s. However, the sensitivity of the equipment that is connected to the grid is now much more sensitive. Therefore, businesses experiencing inexplicable downtime will benefit from eliminating these low-level switching transient events.”<br />
<br />
"It is refreshing to encounter a progressive group of individuals that are truly interested in assisting clients in improving the profitability of their organizations,” said Jeff Edwards, CEO and founder of SineTamer.<br />
<br />
"For too many years, investments made in process technology have failed to reach their promised results, through no fault of their own. It’s simply been due to the electrical environments in which they were placed. With Sinetamer and CP Automation, we look forward to protecting and preserving electronic infrastructure throughout EMEA.”<br />
<br />
Some businesses have already made this investment. In fact, a plant manager at a packaging company was experiencing multiple electrical failures across seven plant areas related to programmable logic controllers (PLC) and power supplies. After implementing SineTamer, the failures decreased from an average of 55 per cent to zero. The improved production saved over $3 million in costs for the facility.<br />

<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
Land-based
diamonds in Namibia are expected to run out with the next decade. To avoid a
shortage, the government of Namibia has been strengthening its offshore diamond
mining capacity. In a joint venture between the Namibian government and De
Beers Group, Debmarine Namibia, the country’s leading marine diamond mining
company, was established in 2002. </div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
The company operates
five diamond mining vessels including the Debmar Pacific, which mines diamonds from
the ocean floor using advanced drill technology.</div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
Having been built
in 1977, the Debmar Pacific was in urgent need of electrical system upgrading. Debmarine
Namibia was having problems with a particular lighting circuit, in which several
transformers were blowing due to suspected poor power quality supply. This is a
classic symptom of an electrical circuit experiencing harmonic noise related
problems.</div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
Actom Energy, electrical
engineering specialist in South Africa, was chosen to design, manufacture and
install an active harmonic filter control panel to the vessel to alleviate this
problem. </div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
Actom needed to
source a harmonic filter fast, and based on a recommendation from De Beers,
called upon <a href="http://www.cpaltd.net/">supply, installation and repair
specialist</a>,<b> </b>CP Automation. Using
the information supplied by Actom and Deers, CP Automation advised the use of an
<a href="https://www.cpaltd.net/adf-p100-active-filter">ADF P100 active dynamic
filter</a> by Comsys. </div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<b>Why are harmonics a problem?</b> </div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
This problem generally
arises from the use of variable frequency drives (VFDs) and other non-linear
loads. A load is considered non-linear if its impedance changes with the
applied voltage. This change means the current drawn by the non-linear load
will not be sinusoidal, even when it is connected to a sinusoidal voltage. </div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
Non-sinusoidal
loads contain harmonic currents that interact with the impedance of the power
distribution system to create voltage distortion and power quality problems, which
heat the transformer. This explains why
the previous transformers broke in the lighting circuit on the Debmar Pacific. </div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
Harmonic filters
— as the name suggests — remove harmonics. However, they also correct the phase
of the fundamental currents, converting non-linear loads into linear ones. They
cancel out the noise and keep the transformers cool and working efficiently. </div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
"We can’t stress enough how much of a
positive impact the right harmonic filter can have on a company’s environmental
performance, lowering energy consumption and improving productivity,” explained
John Mitchell, business development manager at CP Automation. "With this
in mind, we were confident the ADF P100 was a perfect match for Actom's project,
and that it would put an end to the previous transformer issues."</div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
The ADF P100 active dynamic filter also
brings the added benefits of a high-power density while being relatively small
in size, which makes it ideal for small and medium size applications where
space is precious, such as onboard a mining vessel.<o:p></o:p></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
"We would certainly buy from CP
Automation again," said Gregory Webb, instrumentation technician at Actom
Energy. "Installing this filter was straight forward and engineer-friendly.
It has continued to perform well since installation, as demonstrated by the
lack of issues with the transformers in the lighting circuit, as we had seen
before commissioning the harmonic filtering."<o:p></o:p></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
The Debmar Pacific continues its operation
off the southern coast of Namibia. To add to this fleet, the De Beers Group has
since confirmed that the construction of the world's largest diamond mining
vessel has commenced and will begin operation in 2021. <o:p></o:p></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
This new vessel, along with the current
Debmar fleet vessels, will make accessing the millions of carats of marine
gemstones possible, with expert harmonic filtering onboard to ensure electrical
systems are safe, trouble-free and long lasting.<o:p></o:p></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
Namibia’s
land-based diamond excavation may be reaching its end, but now, the country is
taking diamond exploration offshore. With these vessels, the country can
continue reaping the rewards of its lucrative diamond mining industry, without
the limits of the land — or disruptive harmonics.<o:p></o:p></div>

<b style="mso-bidi-font-weight: normal;"><span style="line-height: 200%; mso-bidi-font-size: 10.0pt;">Around 25 per cent of the world's electrical energy is
consumed by electric motors in industrial applications. However, as John
Mitchell, <span style="mso-bidi-font-weight: bold;">global business development
manager at </span></span><a href="http://www.cpaltd.net/">supply, installation
and repair specialist</a>, </b><b><span style="line-height: 200%; mso-bidi-font-size: 10.0pt;">CP Automation explains, installing </span></b><b style="mso-bidi-font-weight: normal;"><span style="line-height: 200%; mso-bidi-font-size: 10.0pt;">variable frequency drives (VFDs) and surge protection devices

<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt;">A Variable Frequency Drive
(VFD) controls the frequency and voltage supplied to an electric motor. By implementing
VFDs, many businesses experience an increased bottom line due to increased
efficiency and reduced energy costs. However, the VFD is not without its
problems — its normal operation can cause negative effects.<o:p></o:p></span></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt;">Issues arise with VFDs due
to power fluctuation. This could be caused by an anomalous event such as a
lightning strike to the grid, or by lower level transient surges caused by VFDs
countless times a day. These transient surges are a change in fundamental
frequency in a microsecond time frame. If not accounted for, they can lead to
confusion in electrical systems, such as false zero crossings, false triggering
of diodes and timing issues. <o:p></o:p></span></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt;">A basic SPD may be used
alongside a VFD to mitigate the damaging impact of high power surges, yet many users
are still faced with unexplainable lockups, downtime and even some failures in
surge protection cause by low level switching transient events. <o:p></o:p></span></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt;">This is because typical SPDs
are voltage triggered only. Their clamping will only occur at a set point above
or below the amplitude of the sine wave, and with therefore not act upon low
level switching transient events. <o:p></o:p></span></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt;">While the sine wave had
remained the same since the late 1800s, the sensitivity of the equipment that
is connected to the grid is now much more sensitive. It's time to bring surge
protection up to speed. It's clear that standard SPDs are not doing enough to
protect valuable systems, whether this is in an elevator, factory conveyor or
petroleum production equipment. <o:p></o:p></span></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt;">The next step is to eliminate
these low level switching transient events. Using surge and transient
protection systems such as the <a href="https://www.ecsintl.com/sinetamer-home/">SineTamer</a>,
offers a new opportunity to protect valuable assets from the transient events
that can occur millions of times per day. The frequency attenuation network of
Sinetamer can do this because it monitors the frequency not just the voltage.<o:p></o:p></span></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt;">Some businesses have already
made this investment. In fact, one plant manager at a packaging company was
experiencing multiple electrical failures across seven plant areas related to programmable
logic controllers (PLC) and power supplies. After implementing SineTamer, the

<br />
We now supply SmartMotion web guide controllers from converting industry component manufacturer, RE-spa. The controllers improve feed accuracy and reduce waste for anyone winding, unwinding or printing on paper, aluminium, plastic or card.<br />
<br />
The SmartMotion controller fuses drive technology with a stepper motor, reducing the amount of wiring and resulting in a single, compact device that can be incorporated into a new machine, or retrofitted to a machine already in use.<br />
<br />
The motor is controlled to 1/128 step, to ensure the system is incredibly accurate, quick and almost silent. The high heat dissipation range of the controller also ensures a constant working temperature, which prevents the device from overheating.<br />
<br />
“When operating a printing press in particular, if the web material is not aligned correctly you’re wasting production time and potentially creating unnecessary waste,” said Tony Young, director of CP Automation. “RE-spa web guides eliminate this problem. It uses a sensor to monitor whether the edge of the material is in line and automatically adjusts if not.<br />
<br />
“People often consider automation as a large investment in robotics or artificial intelligence (AI). But, in truth, adding something simple like the SmartMotion controller improves the automated process and can save you time and money by reducing scrap material.”<br />
<br />
The controller can be supported by a WLigo display, which has been developed to support applications where there are more than one web guide system installed in a facility. This means that plant managers can control and manage all parameters of a system from one remote controller.<br />
<br />
RE-spa web guide systems are available from CP Automation, along with the full range of converting machine automation equipment from RE-spa. To find out more about the RE-spa range, call +44 (0)1724 851515 or email sales@cpaltd.net.<br />

<br />
CP Automation is strengthening its already existing product family, having supplied EMC filters, line and motor chokes and braking resistors to the crane industry for many years. As the company continues to serve the market, its work with VASCAT and Magnetek provide further opportunity to take advantage of market growth.<br />
<br />
"Our partnership with CP Automation has evolved over the years," said Jan Santaló, drives segment sales manager at VASCAT. "Alongside Magnetek, we are making it much easier for crane OEMs to source the components they require.<br />
<br />
"VASCAT motors can be either used as part of modernisation projects or integrated into new crane designs. What sets us apart is that we customise our motors to suit the specific crane application, and we conduct the necessary validation tests to ensure safety and longevity."<br />
<br />
CP Automation also supplies radio remote control systems in partnership with Magnetek. This complements the movement away from cab controlled cranes, where-by the operator sits in the crane guided by hand signals from a floor walker, to radio control systems that use a cordless unit to direct the crane. This means the operator is out of range of load swings and potential drop loads.<br />
<br />
"The partnership brings together the right set of products to support the current rapid growth of the crane industry," explained Andy Swann, business development manager EMEA at Magnetek.<br />
<br />
"We are seeing more and more crane OEMs moving away from in-cab operators and opting for radio remote control. This safe distance means much more aggressive materials can be handled during a project, as well as providing the freedom of movement to gain better visibility."<br />
<br />
Magnetek also manufactures collision avoidance systems, power delivery systems and failsafe brakes for added safety functionality.<br />
<br />
It you are a crane OEM, rebuilder, repairer or end user looking to source a collision avoidance system, radio remote control system or motor, you can call +44 (0) 1724 851515 to speak to a member of the technical team at CP Automation about both VASCAT and Magnetek components. </div>

<br />
<div>
<div style="text-align: start;">
<span style="text-align: justify;"><b>We have</b></span><b style="text-align: justify;"> a new range of harmonic filters available, including the Revcon RHF-A and
RHF-B. These filters are used to reduce the harmonic distortion caused by variable
speed drives (VSD). To make sure the performance claims of these filters are valid,
CP Automation analysed both filter models in a series of tests. </b></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
VSDs make
harmonic noise. This noise goes back to the transformer and affects the signal
generated. This in turn distorts the voltage, leading to overheating of the
entire system. Harmonic filters reduce this noise in the first instance,
prolonging the life of all equipment.</div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>

<br />
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
CP Automation's
new range of Revcon passive harmonic filters are easy to retrofit into existing
applications, with no need for routine maintenance. Revcon states that the
RHF-A and RHF-B reduce harmonic current distortion to 10 per cent and 5 per
cent respectively. However, these figures have been cross referenced as part of
a test with a standard 6-pulse VSD and DC choke.</div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
Without a
harmonic filter, findings showed the drive created a harmonic distortion of 36
per cent. Positively, the RHF-A reduced this harmonic distortion to 6.2 per
cent at nominal operation. Similarly, the
RHF-B reduced the harmonic distortion to 2.5 per cent. Both performance values
demonstrated far better results that the official stated values from Revcon. </div>

Projects was undertaking a 17 month project in Windhoek, the capital of Namibia,
to alleviate a critical water shortage. Using boreholes, a deep, narrow hole
made in the ground to locate water, the client pumped water to various
reservoirs. This is to provide an accessible store of water for Windhoek. <o:p></o:p></span></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">

<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">To
power the pump system, Rockwell Automation delivered eight Allen-Bradley
Powerflex 753 low voltage AC drives, varying from 250kW to 132 kW. However, to
use these variable speed drives (VSDs) at depths of 150 to 250m, the company
also needed to source sine wave filters. This is why the team reached out to CP
Automation, which supplies and installs a range of sine wave filters for
different applications.<o:p></o:p></span></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">

<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">Sinewave
filters are used where variable frequency drives are installed with extremely
long motor leads, as used with the depths of these boreholes. Due to an
impedance mismatch, a portion of a high frequency wave is reflected back in the
direction from which it arrived. When the reflected edges encounter other wave
edges, their values add, causing voltage overshoots. <o:p></o:p></span></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">Sine
filters reduce the edge steepness of the waves, meaning these edges can no
longer accumulate. This prevents </span>premature motor failure caused by
damaging voltage overshoots<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">.<o:p></o:p></span></div>

these sine wave filters, safety and power supply would be compromised,"
explained John Mitchell,</span> <span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">global business development manager
at CP Automation. "The filters eliminate high frequency content and
voltage peaks generated by the variable frequency drive, thereby reducing motor
heating and extending the motor life. If these waves were not converted, voltage
overshoots could have halted this incredibly important project for the Namibian
community."<o:p></o:p></span></div>

<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
"The long
motor cable lengths meant the sine filters reduced parasitic

higher the risk of damage to an incredibly expensive piece of equipment. <o:p></o:p></span></div>

<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">Just
before the company deployed the drill for the first time, faults with the winch
began to appear. Onboard engineers found the problem to be a DC BUS overvoltage
issue caused by the brake chopper. The engineers attempted to alleviate the
problem by replacing the brake chopper like-for-like, but their attempts proved
unsuccessful. <o:p></o:p></span></div>

<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">After
calling a representative from the brake chopper manufacturer, they agreed to
fly out as soon as possible. Unfortunately, due to time constraints, this
meeting was cancelled, leaving the project losing tens of thousands of dollars
every day and those on board no closer to rectifying the problem. <o:p></o:p></span></div>

<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">By
the time the company contacted CP Automation, the drill had been out of action
for two weeks and the crew were at wits' end.

<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">The
winch system controls the deployment of the drill to the seabed, which could be
up to 3km from the ship. The winch also provides under tension — keeping the
cable taught during payout. The brake chopper unit, rated at 400KW continuous
600A and 600KW, 900A at peak, dissipates the excess DC BUS voltage fed back from
the motor. <o:p></o:p></span></div>

<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">If
the winch cannot dump the energy created during this process into the braking
resistors because the brake chopper has a fault, then the operator can't
control the cable. This would result in the loss of a drill worth millions of
pounds. It was therefore imperative that the brake chopper was reliable before
the crew deployed the drill. <b><o:p></o:p></b></span></div>

<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">Once
the drill is in the water, the application provides active heave, compensating
for the wave movement by automatically driving the winch in the opposite
direction at the same speed to stabilise the drill. The drill has to remain at a constant height
from the sea floor so that it can clamp in position. <o:p></o:p></span></div>

<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">Because
time was of the essence, CP Automation flew out to Japan as soon as we could. We
powered up the application when the boat was docked and the brake chopper
exhibited new sets of faults each time we tested. It was difficult to test
under working conditions because we were unable to deploy the drill, which
would work the winch motors. It was therefore impossible to tell if there were
any electrical noise problems, which was our suspicion. <o:p></o:p></span></div>

<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">CP
Automation removed the existing brake chopper and fitted its own 100KW unit
into the system. The fault did not transfer to our product, but reoccurred when
we reinstalled the old unit. <o:p></o:p></span></div>

<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">Because
the ship's crew identified a window when the sea would be calm enough to live
test the drill, we were unable to carry out any more tests in dock. <o:p></o:p></span></div>

it was possible to assess the current required during payout and active heave.<o:p></o:p></span></div>

<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">To
fit the two brake choppers, we had to modify the control panel. This required
us to split the DC BUS into two, with drives one and two on DC BUS one and
drives three and four on BUS two. <o:p></o:p></span></div>

<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">This
provided the system with an element of redundancy it did not have before. There
was now the option that, should anything go wrong, the crew could operate the

<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">After
more tests in mild waves of 1.4m in height, the brake choppers were pulling 30A
max per unit during active heave when the drill was at 750m from the ship. The
DC bus level was maintained below 750VDC the whole time, which proved that the
replacements were a proficient fix. <o:p></o:p></span></div>

client deployed the drill five times throughout the twelve hours and the system
ran smoothly every time. As far as we could tell, there were no more issues relating
to the brake choppers and the crew were able to extract all the mineral samples
necessary. <o:p></o:p></span></div>

<span style="line-height: 200%; mso-bidi-font-size: 10.0pt; mso-bidi-font-weight: bold;">After
careful testing, we proved that CP Automation's brake choppers worked in the drill
application because, unlike the original unit, our brake choppers did not use
external power controls. This meant they are not susceptible to external noise.
The previous brake chopper had no electromagnetic compatibility (EMC) or
harmonic filter installed, so the resultant electrical noise from the drill
application and those around it, caused the brake chopper to fault. <o:p></o:p></span></div>

<span style="line-height: 200%; mso-bidi-font-size: 10.0pt;">Scientists, fiction writers
and film directors often refer to the oceans as the last frontier because of
just how little we know about their depths. Indeed, deep-sea mining is still
only in its infancy; scientists predict that minerals could be in abundance
under our unexplored seas, albeit difficult to extract.<o:p></o:p></span></div>

Automation managed to revive is one of the first of its kind to sample valuable
metals from tough volcanic rock. With the help of more research and investment,
this method of mining could lead to a healthy flow of essential resources for
years to come. <o:p></o:p></span></div>

<b>CP Automation now supplies Vascat's latest addition to
its industrial motor portfolio; the new MAC QTW motor range designed
specifically for low noise applications. This product launch will be

<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
End of line
testing is a critical step in the production process. Defective products are
separated from functional units by analysing the products vibro-acoustic
behaviour pattern. This data provides crucial information regarding the
condition of the product. However, any external ambient noise can corrupt this
analysis resulting in unreliable results, which explains why a low-noise motor
is required. <b><o:p></o:p></b></div>

<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
"The MAC
QTW motors have been designed specifically with test systems in mind,"
explained Xavier Palomar, sales and marketing manager at Vascat. "We want
to increase reliability in end of line testing, and minimise false rejection of
products."</div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">

<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
"If
businesses are rejecting perfectly good products because of false negatives,
then money is going down the drain," added John Mitchell, global business development
manager. "Confounding motor noise will no longer be an issue with this new
range. We are pleased to be maintaining our long standing partnership with
Vascat as part of this unique product launch."</div>

<br /></div>
<div class="MsoNormal" style="line-height: 200%; text-align: justify;">
MAC QTW motors
are liquid-cooled, meaning they have higher efficiency compared with air-cooled
motors. This further adds to the cost-savings already gained from reliable end
of line testing. Added safety benefits also come from the IP23 protection
rating and electrically insulated bearing within the motor. </div>

Fans don’t normally need a <a href="http://www.cpaltd.net/resistors_brake_chopper.php">braking resistor and chopper</a> but when they are operating in a closed system, a situation may arise where one fan will over-speed the next and the DC bus voltage on their motor drives will then rise. Here John Mitchell of <a href="http://www.cpaltd.net/">CP Automation</a>, reports on the case of <a href="http://www.ga-petfoodpartners.co.uk/">GA Pet Food Partners</a> in Leyland, Lancashire. <br />
<br />
External dynamic braking choppers are useful to drive manufacturers, panel builders and end users alike. A seventh IGBT (Isolated-Gate Bipolar Transistor) for the chopper in a six-pulse drive is one way drive manufacturers can reduce the cost of the product by rating the IGBT to a given torque and duty level. Some six-pulse off-the-shelf AC drives manufactured today have a seventh IGBT built in as standard. <br />
<br />
The calculation for sizing the internal brake chopper is not a difficult one, but getting accurate data in the first place can be. Some brake choppers on board a drive range from 25% to 100% ratings. And let’s not forget the fact that not all drive manufacturers fit a seventh IGBT above ratings of 22kW. <br />
<br />
To this end, where it is too expensive to change the installed drive or where regenerative energy has been overlooked, CP Automation offers a range of external brake choppers that covers 99% of application needs up to 360kW peak, 100kW continuous. <br />
<br />
Available in nine models across three frame sizes, there are several options to set the threshold to the desired switching level, along with fault output and master-slave options to chop higher power levels. <br />
<br />
External brake chopper units should allow for a fit and forget procedure. During emergency stops the unit will still function – because it is powered by the DC bus and not by an external supply. These were key features for a fan application at GA Pet Food Partners. <br />
<br />
GA Pet Food Partners works with some of the biggest pet food businesses in the world. However, it doesn’t manufacture an own label product because it doesn’t believe in having an own brand. It sees itself as a partner, not a competitor, to its customers. <br />
<br />
From concept to launch and storage to dispatch, the company claims it partners with more private label pet food brands than any other pet food manufacturer, making it easy and profitable for pet food brands to launch and grow their business. <br />
<br />
GA Pet Food Partners operates an environmental extraction system comprised of three parallel 185kW ABB Motors spinning the Halifax fans cascading into smaller fans, and was encountering difficulty in decelerating the biggest of these units. The effect of over-speeding becomes cumulative the more fans there are in close proximity on a factory floor. <br />
<br />
The three large fans are controlled by Allen Bradley Powerflex 753 variable speed drives (VSDs) from Rockwell Automation, which count among their features predictive diagnostics to extend the life of cooling fans. <br />

“In an environmental extraction system, if a fan runs too fast, it either pressurises air too much at one end or creates suction at the other,” explained Jayne Whittaker, engineering director at GA Pet Food Partners. <br />
<br />
“Some machines on the shop floor have exhaust fans, which need to run at the appropriate speed. CP Automation supplied external brake resistors and retrofitted brake choppers within the existing panels that house the Allen Bradley drives.” <br />

<b>Advanced extrusion </b><br />
<br />
The new GA Pet Food Partners factory is home to the most technically advanced extrusion plant in the world, making some of the finest super premium dry pet foods. GA Pet Food Partners has invested in the world’s first thermal twin extruder, which allows it to include very high levels of fresh meat in premium dry pet foods without the use of dry meat meals. <br />
<br />
With four extruders, the company has a production capacity of 100,000 tonnes of super premium pet food and can make batches from 3-200 tonnes to suit small or large brands, delivering the same quality and consistency whatever the batch size. <br />
<br />
A reliable electrical equipment provider should have a clear understanding of the application as a whole, the machine itself and the components. This way, CP Automation is able help make the manufacturing process more efficient, more cost effective and more sustainable in every sense.<br />

Fresh from the manufacturer, most drives — even ones with onboard brake choppers — are not rated sufficiently for the braking demand of the application. Here, John Mitchell of <a href="http://www.cpaltd.net/">CP Automation</a>, discusses the benefits of using a universal brake chopper that works with any inverter. <br />
<br />
Non-specialist engineers face an extremely complex task when asked to choose the correct inverter, resistor and brake-chopper combination for a project. <br />
<br />
To help counteract this problem, CP Automation recommends using an external brake chopper unit that simplifies the process of inverter selection. Where an inverter doesn’t feature a built-in brake chopper, the new CP Automation unit, manufactured to the highest standards, supplies that functionality. It’s a universal model that works with any inverter, from any manufacturer. <br />

<br />
However, the fact that a product is universal doesn’t simplify the selection process by itself. You also need to ensure that you choose the right integration and maintenance partner, so you are not tied into a limited range of drives from a limited range of manufacturers. <br />
<br />
A good maintenance partner will provide an honest view of whether you already have the correct resistor and, if you don’t, supply one as part of a package to help meet your specific objectives. <br />
<br />
For instance, if the original inverter already has a brake chopper onboard it may be that the Ohmic value of the existing resistor doesn’t meet the criteria of the new one. This can lead to damage to the drive system and its environment and in worst-case scenarios, create health and safety problems. <br />
<br />
CP Automation's universal unit is very flexible and extremely simple. The maintenance engineer simply connects two wires from the drive’s DC Bus and two wires from the resistor, and the system is up and running. <br />
<br />
An additional benefit of the product’s universal nature is that, should you install a brake chopper and inverter package and the inverter then fails, the end user can simply install any drive, from any manufacturer. The brake chopper and resistor package doesn’t tie the user to certain equipment, as the equivalent bought direct from the drives manufacturer would. <br />
<br />
This means manufacturers can bring a production line back to full service quicker than if the brake chopper and resistor package worked with only one inverter model. <br />
<br />
It is also possible to re-deploy inverters in use on less critical equipment to mission critical applications without fear of incompatibly. CP Automation's brake chopper even finds applications in motion control drive solutions, where it is equally applicable due to the common DC bus. <br />
<br />
A DC bus drive system configuration provides users with significant advantages including design flexibility, higher efficiency and inverter power sharing as well as cost savings. These are realised through reduced cabling and fewer components — such as resistors and thermal devices. <br />
<br />
CP Automation routinely keeps extensive stocks of brake choppers in its warehouses, with the smallest unit being 11kW continuous, 33kW peak, and the largest being 100 kW continuous, 360kW peak and users can parallel up above this to create BC units greater than 1MW. <br />
<br />
In the drives industry there is a genuine belief that all AC inverters are created equal. This situation is exacerbated by the fact that inverters are often bought as commodity items, much like control gear. But the reality is that, at least with regard to dynamic braking, this couldn’t be further from the truth.Anonymoushttp://www.blogger.com/profile/10068463984446977647noreply@blogger.com0Scunthorpe, UK53.588646 -0.6544129999999768253.513232499999994 -0.81577449999997675 53.6640595 -0.49305149999997683tag:blogger.com,1999:blog-707492685717360608.post-54425387659054415002017-05-23T08:00:00.000+01:002017-05-23T08:00:39.835+01:00The brake chopper size conundrum<!-- AddThis Button BEGIN -->
Many drives manufacturers design and build their products with a seventh Insulated-Gate Bipolar Transistor (IGBT), in the form of a brake chopper, incorporated into the device. Here, John Mitchell, global business development manager of <a href="http://www.cpaltd.net/">CP Automation</a>, looks at the dangers of taking your IGBT for granted.<br />
<br />
Manufacturers often include a brake chopper up to a certain size of inverter, but beyond that size, they will expect customers to use an external unit. However, to reduce the cost of the drive to the end user, the seventh IGBT isn’t necessarily rated to the full power rating of the drive itself. <br />
<br />
Most inverter manufactures will argue that the cost benefit of not rating the IGBT to the full capacity of the drive is more than worth the loss of braking capacity. Furthermore, there is an argument that this is a legitimate design decision - manufacturers will claim that a very high percentage of end user applications don’t actually the full braking capacity. <br />
<br />
In very light duty applications, such as emergency stop applications for instance, underrating the built in brake chopper wouldn’t be a problem. In fact, anything that is up to ten per cent duty will be very unlikely to suffer any kind of issue at all.<br />
<br />
In contrast, any kind of application where the drive system has to stop and start regularly, such as an elevator or conveyor, needs to pay more attention to the brake chopper. <br />
<br />
The real problem is not the manufacturer’s decision to install a low capacity IGBT but the decision not to make this information very clear in the manual and the accompanying documentation. <br />
<br />
The key point in any application is that the mechanical stopping of the load is just as important as selecting the drive system. <br />
<br />
For instance, a fifty-metre crane that lowers at half a metre per second will clearly take 100 seconds to lower fully. It may only do that twice a day, but when it does, it is operating at full capacity - not 30 per cent or 50 per cent. From a chopper and resistor point of view, that is a continuous period that the drive's onboard brake chopper couldn’t cope with.<br />
<br />
The drive manufacturer might argue this only represents 20 per cent duty, but that’s where the application knowledge of the integrator or maintenance team becomes crucial. During the 100 seconds of descent, the application is dumping more and more energy and the resistors are getting hotter and hotter. It could be quite dangerous to attempt this kind of application with an inadequately sized internal seventh IGBT.<br />
<br />
The bottom line is that brake choppers should be sized for the worst case, not the cumulative case.
