General
Eaton's Cooper Power Systems all-film, unfused
capacitors (Figure 1) feature extended-foil elements,
solderless connections, and laser-cut aluminum foil
(folded foil optional) in a high stacking factor design.
Designed, manufactured, and tested to meet or
exceed the requirements of IEEE Std C18™-2002
standard (Heavy-Duty and Extreme-Duty capacitors
tested to IEEE Std C18™-2012 standard), these
capacitors are a simple, economical, and reliable
source of reactive power on outdoor or indoor
electric power systems for:
Power capacitors can be installed singly or in
factory-assembled switched or unswitched banks

Medium voltage standard-duty, heavy-duty, and extremeduty single-phase, unfused capacitor units and accessories
Standard-duty (SD Type) capacitors
Construction Features
Capacitors are intended to be operated at or below their rated
voltage. All capacitors are designed with a continuous overvoltage
capability of 110% of rated voltage and meet IEEE Std 18™-2002
standard. This overvoltage capability is to allow the capacitor to
withstand bank and system contingencies such as bank unbalance
and system voltages higher than the rated maximum continuous
operating voltage.
Construction features of Eaton's Cooper Power Systems power
capacitors include:
Standard-Duty capacitors are designed for typical utility transmission
and distribution applications.
•
Stainless-steel tank with light-gray finish for resistance to severely
corrosive atmospheres
•
Light-gray, porcelain bushings; glazed for high strength and durability and hermetically sealed to the capacitor tank
•
Stainless-steel mounting brackets with industry-standard 15.62in. mounting center for unit interchangeability; under-side of each
bracket is unpainted for positive grounding
•
Parallel-groove terminals accommodate copper or aluminum conductors from No. 8 solid to No. 1 stranded
•
Parallel-groove connectors are supplied on all capacitors sold as
individual units. The parallel groove connector should be removed
and discarded on capacitors used as replacements in substation
bank applications on which a leader ejection spring and associated hardware are used with an expulsion fuse. See Service
Information S230-30-3 Expulsion Fuse Installation Instructions for
detailed information.
•
Internal discharge resistors that reduce terminal voltage to 50
volts or less within five minutes after the capacitor has been disconnected. Other discharge criteria are available.
•
Stainless-steel nameplate includes all required information per
the applicable standard. In addition and for ease of maintenance,
both the nominal capacitance and the measured capacitance are
included on each nameplate.
•
Blue non-PCB decal
Standard-Duty Ratings
•
110% continuous rms overvoltage capability
•
10 kA fault handling capability
•
Standard temperature rating -40 to +55 °C (-50 °C available,
consult factory)
Table 2 lists the ratings and catalog numbers for the Standard-Duty
single- and double-bushing capacitors. Other unit kvar, voltage,
frequency, and BIL ratings are available.
Heavy-Duty (HD Type) Capacitors
Heavy-Duty designs meet or exceed IEEE Std C18™-2012 standards.
Heavy-Duty capacitors are designed for applications where higher
reliability is desired (Ex: Transmission Capacitor Banks). The HeavyDuty Capacitor is more resistant to the effects of higher transients,
harmonics, and voltage excursions than the Standard-Duty Capacitor.
Heavy-Duty Ratings
•
125% continuous rms overvoltage capability
•
135% peak overvoltage capability

Extreme-duty (XD Type) capacitors
Extreme-Duty capacitors are designed to exceed the IEEE Std
C18™-2012 standard. These capacitors are designed for the most
extreme harmonic environments, and are the perfect choice for
application on systems with unknown contingencies (Ex: Industrial
applications).

EX™-7Li and EX-7Fi single-phase
internally fused medium-voltage
capacitor units
General
EX™-7Li and EX-7Fi all-film internally fused
capacitors feature Eaton's Cooper Power Systems
design innovations; extended foil, solderless connections, CLEANBREAK™ element fusing system
and both laser-cut and folded edge aluminum foil.
Designed, manufactured, and tested to meet or
exceed the requirements of all applicable ANSI®,
IEEE®, and IEC standards, their low cost per kvar
makes these capacitors a simple, economical
source of reactive power on electric power systems for:
•
Power factor correction.
•

At the substation, to supply the system kvar needs most
effectively.
•
At or near the load center, to obtain the optimum kvar supply and
voltage correction.
•
At the end of the line, to achieve maximum voltage correction.
•
In series with a distribution feeder to minimize flicker and provide
voltage support.
•
In series with a transmission line to minimize the reactance of the
line, improving stability and controlling voltage drop.
Ratings
Capacitors from Eaton's Cooper Power Systems are rated in
continuous kvar, voltage, BIL and frequency and are subjected to
all applicable ANSI®, IEEE®, or IEC routine tests. The capacitor unit
rated voltage is the voltage at rated frequency that can be applied
terminal-to-terminal continuously. See the standard to which the
capacitor unit is manufactured for guidance in operation above rated
voltage.
Single-phase capacitor units are designed to produce rated kvar at
rated voltage and frequency within the tolerance of the applicable
standard. As the capacitor’s kvar output is proportional to the square
of the applied voltage, proper application requires attention to the
applied voltage.
Available capacitor unit ratings can be obtained by contacting the
factory.
Construction features
Construction features of Eaton's Cooper Power Systems power
capacitors include:
•
•
CLEANBREAK element fusing system. Each element is protected
with a series connected CLEANBREAK current limiting fuse. This
patented fusing system incorporates the following features:
• Polymer fuse card provides isolated fuse mounting which
prevents potential damage to adjacent capacitor elements and
fuses.
•
Fuses are individually mounted within a polymer fuse tube. The
tube protects the fuse from damage due to adjacent element
failures and fuse operations. This design also requires no paper
in the fusing dielectric, thereby eliminating the generation of
extensive carbon arc by-products in the dielectric fluid. This
significantly improves the dielectric performance by preventing
fluid contamination and promotes proper clearing of element
fuse.
•
The CLEANBREAK fuse operates in a current limiting mode to
chop the fault current into the failed element. This prevents the
energy stored in the parallel connected elements from being
discharged into the fault thus minimizing gassing and damage
to the failed element and adjacent dielectric.
EX® mechanical connection system. Provides solderless internal
connections that eliminate localized heating and cold solder joints.
The EX crimping system also allows 100% inspection during
assembly assuring integrity of internal connections and maximizes
operational safety.

Fuseless capacitor banks
General
Fuseless capacitor banks from Eaton's Cooper
Power Systems feature the latest capacitor
technology, the Standard-Duty (SD), Heavy-Duty
(HD), and Extreme-Duty (XD) all-film capacitors.
The banks are designed to meet or exceed all
applicable ANSI®, IEEE®, NEMA®, and IEC
standards. The industry demand for more reliable
and lower total life cycle cost (TLC) capacitor
equipment has essentially made the fuseless
capacitor bank the standard for substation
applications at 34.5 kV and higher. Fuseless banks
have been offered since the late 1980s and are not
a new technology, but an application of an existing
technology, the all-film capacitor introduced by
Eaton's Cooper Power Systems in 1971. Fuseless
capacitor banks offer the following advantages:
• Low initial and operating costs
• Low losses
• Small footprint
• Ease of unbalance protection
• Ease of installation and maintenance
• Increased protection against animal faults
• Increased reliability and availability
• Ideal for harmonic filters

Fuseless capacitor banks
Effective June 2014
Description of operation
The SD, HD, and XD capacitors are constructed internally of
smaller capacitors called elements arranged in series and parallel
combinations to achieve the voltage and kvar rating of the unit.
Figure 2 illustrates how the individual elements are arranged to
form a complete capacitor unit. The elements are constructed
of aluminum foil electrodes with a dielectric of electrical grade
polypropylene. The SD, HD, and XD capacitors exhibit a benign, or
safe, dielectric failure mode. It is this safe failure mode that is the
key to applying the capacitor units without the need for additional
fusing.
In the rare event the polypropylene dielectric fails, the energy in the
resulting small arc punctures many layers of the thin film and foil
within the element. The arc causes the film layers to recede allowing
many layers of the aluminum foil electrodes to touch and weld
together forming an extremely stable electrical joint. This welded
aluminum electrical joint exhibits very low losses and is capable of
carrying, indefinitely, without gassing or thermal degradation, the
full capacitor unit rated current, and transient currents associated
with normal operation. The result of a failed element is that an entire
series section is shorted.
Figure 3 is a schematic of a fuseless capacitor bank connected in
a grounded double wye configuration. A fuseless capacitor bank is
constructed of one or more strings of series connected capacitor
units. If one element within a capacitor unit fails, the series section
in which it is located is completely shorted. The resulting increase
in current through the capacitor unit is very small and thus the
increase in voltage applied to the remaining series sections in the
string is correspondingly very small. The safe failure mode of the SD,
HD, and XD all-film capacitor units allow them to remain in service
with shorted series sections.
Low cost
results in lower installation costs and allows the user to realize
the economic benefits of the capacitor faster.
3. Fuseless banks have no fuse I2R losses resulting in lowest operating costs and longest capacitor life.
4. Field maintenance is reduced as periodic capacitance
measurements are not required and defective capacitor
units are easily located by a few capacitance measurements.
Further, nuisance fuse operations are eliminated that result in
unnecessary alarm and trip conditions.
Losses
A fuseless capacitor bank has approximately 40% to 50% fewer
losses than those of a comparable internally fused capacitor bank
and approximately the same or slightly lower losses than that of a
comparable externally fused capacitor bank using expulsion fuses.
This can result in significant annual power savings. Any comparison
between fuseless and internally fused banks should include the
effect of losses on the operating costs.
Also, fuseless capacitors operate at a significantly lower internal
temperature rise than internally fused capacitors. The cooler
operating conditions of the all-film fuseless capacitor not only means
lower energy consumption, but also indicate greater reliability and
longer useful operating life of the dielectric system.
A capacitor is an electrochemical device that has no moving parts
and, in performing its useful function, is acted upon by temperature
and electrical stress. The combinations of electrical stress and
temperature stress drive the mechanism by which capacitors wear
out and come to the end of usefulness. The result of capacitor wearout is always dielectric breakdown and failure. Thus, low operating
temperatures are important since the chemical reaction of the wearout mechanism will occur at a slower rate resulting in long useful
dielectric life.
Fuseless capacitor banks have the lowest combination of initial and
operating costs.
1. Fuseless banks require no fuses and have minimal structure and
buswork thus minimizing land usage within and transportation
costs to the substation.
2. Fuseless banks are easy to install due the low number of
connections and the low current nature of the connections. This

Small footprint
Fuseless banks are ideal in applications where installation space
is limited. There is no requirement for extra clearance for fuse
expulsion gasses or for a minimum number of parallel-connected
capacitor units. Fuseless banks are ideal for indoor applications.
Capacitor Bank Protection
Fuseless capacitor banks have two modes of protection:
1. The primary mode is the stable short circuit of a failed element.
A capacitor unit may operate indefinitely with a shorted series
section as long as the overvoltage on the remaining series
sections is within allowable limits.
2. The secondary mode of protection is affected with protective
relays. Protective relaying increases bank availability by warning
personnel of potential problems in the bank and by removing the
bank from service before severe damage occurs.
Overcurrent and overvoltage protection of a fuseless capacitor
bank is affected in a manner identical to fused banks. Unbalance
protection for a fuseless capacitor bank is very simple as failed
elements result in the shorting of entire series sections. This
allows for greater sensitivity in failure detection than a comparable
internally fused bank.
The design of the protective relaying begins with bank design.
Eaton's Cooper Power Systems Edison™ Idea™ protective relay
platforms are the state-of-the-art in microprocessor based relays
for capacitor bank protection. With these relays, all capacitor bank
protection, control, communications and monitoring needs can be
economically met.
Installation and maintenance
Fuseless capacitor banks are easy to install. Most of the
interconnections between capacitors are factory assembled so
fewer electrical connections are required during installation.
Fuseless capacitor banks utilize simple and efficient unbalance
detection methods. The capacitors used in fuseless banks are
designed with a small number of large capacitor elements.
Therefore, element failures provide sufficient impedance change
such that they can be detected by simple relaying schemes.
Eaton's Cooper Power Systems fuseless capacitor banks are virtually
maintenance free. Periodic measurements of capacitance are not
required for all but the very largest banks with unbalance detection
schemes susceptible to ambiguous indication. However all capacitor
banks should be, at least, visually inspected periodically. See Service
Information S230-30-4, Fuseless Block Bank Installation Instructions,
for recommended maintenance items.
Locating capacitor units with shorted series sections in a fuseless
capacitor bank requires some capacitance measurements.
However, these measurements are few and relatively easy. The
measurements may be taken with a simple low voltage meter.
Reliability and Availability
The following features of fuseless capacitor banks from Eaton's
Cooper Power Systems maximize the reliability and availability of
your capacitor bank installations.
1.
Animal Protection: Optional protective caps for the
capacitor unit bushing terminals and protective tubing for the
interconnecting wire are available to minimize exposed live parts
thus reducing the potential for external flashover due to birds or
other animals.
2. No Fuses: Spurious fuse operations and the i2R losses
associated with the fuses are eliminated in fuseless capacitor
bands. With no internal fuses heating the dielectric, fuseless
capacitor units have the longest dielectric life.
3. Low Maintenance: Periodic maintenance is minimized.
The unbalance detection schemes used for internal fused
banks, typically, cannot detect the first or second internal
fuse operation and thus are susceptible to fuse operations
distributing themselves throughout the bank and maintaining
a level of unbalance undetectable by the unbalance relaying
scheme. This is known as ambiguous indication. Because of this,
internally fused banks require periodic maintenance to locate
partially failed capacitor units.
The unbalance detection schemes used for fuseless banks,
typically, will detect the first series section short. This allows for
maintenance to be scheduled at the owner’s convenience and
eliminates the possibility of dielectric failures distributing
through the bank undetected. Therefore, periodic maintenance
to locate partially failed units is not required. Fuseless banks are
virtually maintenance free.
4. Ease of Maintenance: Locating a partially failed capacitor unit
in a fuseless bank is very easy, especially when compared
to internally fused banks. A readily available, low voltage
capacitance meter is used to isolate the string containing the
faulted capacitor unit. From there, individual unit capacitance
measurements are made to locate the faulty capacitor.
Determining if an individual fuseless capacitor unit is faulty
is also very easily accomplished. A partially failed fuseless
capacitor unit will typically have a capacitance that is > 11%
higher than its original capacitance and thus is easily detectable
with a simple, low voltage, hand held capacitance meter.
The location of a partially failed internally fused capacitor unit
requires a capacitance measurement of every capacitor unit.
However, this is not a simple capacitance measurement
because the decrease in capacitance of a typical internally fused
capacitor unit with an operated fuse is only 1 to 2%. To properly
identify a partially failed internally fused capacitor unit, its
capacitance measurement must be correctly for temperature
and compared to previously recorded values.
Fuseless capacitor units are typically 20% smaller and lighter
than a comparable internally fused capacitor unit thus making
their handling easier.
5. Simplicity: Fuseless capacitor banks from Eaton's Cooper
Power Systems are the “keep it simple solution” to your
capacitor banks needs. Unbalance relaying and maintenance are
simplified and useful life is extended. Also, fuseless capacitor
units typically have 1/4 to 1/3 the number of elements and about
1/5 the number of internal connection points of an internally
fused capacitor unit. The simplicity of fuseless capacitor units
equates to greater reliability.
Harmonic filters
Fuseless capacitor banks are an ideal choice for application in harmonic filters for the following reasons:
1. The change in capacitance as a result of a dielectric failure is
small thus the tuning of the bank changes very little.
2. The capacitance of fused capacitor banks decreases as fuses
operate shifting the tuning point of the filter to a higher
frequency. This may move a parallel resonance to a frequency
with a harmonic content and thus result in an unacceptable
voltage distortion. For this reason, harmonic filters using fused
capacitors are typically tuned below the frequency to be filtered.
The shorting of a series section in a fuseless capacitor bank
increases its capacitance thus shifting the tuning point of the
filter to a lower frequency. This typically moves the parallel
resonance away from frequencies with a harmonic content and
allows harmonic filters to safely be tuned close to the desired
frequency for optimal performance.
3. Harmonic filters are often subject to large dynamic overvoltages
www.cooperpower.com
230-31-3
Technical Data 230-31
Fuseless capacitor banks
Effective June 2014
due to switching of the filters or other components such as
furnace transformers. These overvoltages often exceed the
capability of the fusing in the event of a dielectric failure during
the overvoltage. This is not an issue with fuseless banks because
of the safe failure mode of the all-film capacitor. In addition,
the string configuration of fuseless banks inherently minimizes
the parallel energy discharge, which can result in the failure of
external and/or internal fusing systems.

current-limiting fuses coordinate with the capacitor tank rupture
curves. These fuses are electrically mounted at the inside terminal
of the bushing well or bushing for the deadfront option or at the
incoming NEMA® terminal for the livefront option. The fuses protect
all equipment in the pad-mounted capacitor bank with the exception
of optional arresters which are connected to the source side of the
group fuse and optional control power transformers which will be
protected with their own fuse. For grounded wye bank ratings that
cannot be group fused, the bank will be configured with 2 capacitor
units per phase and each capacitor individually fused.
In an ungrounded wye connected bank, the faulting of a capacitor
unit to a short circuit, results in an increase in phase current by a
factor of 3. At this relatively low current, a fuse selected for group
fusing may take several minutes to clear and during this time, the
capacitor units in the other two phases are experiencing a 1.73 PU
overvoltage as they are now connected lie-to-line and the shorted
capacitor unit is experiencing three (3) times nominal phase current.
It is highly desirable to minimize the duration of this overvoltage and
overcurrent. Therefore, for ungrounded wye banks, Eaton's Cooper
Power Systems standard offering will use individual fusing and two
(2) capacitor units per phase. In the standard configurations with
only two (2) capacitor units per phase, there is a 20% increase in
voltage on a capacitor when the fuse on the other capacitor unit
in the same phase operates. Because of this, only the Heavy Duty
and Extreme Duty capacitors will be offered for ungrounded wye
capacitor banks due to their ability to handle a 125% continuous
overvoltage.
Group fusing is standard for all delta connected banks. Individual
capacitor fusing is not offered as a standard option for delta connected banks.
When individual capacitor unit fuses are applied, the rest of the
equipment between the capacitor fuses and the inside terminal
of the bushing well or bushing for the deadfront option or at
the incoming NEMA® terminal for the livefront option should be
protected by fuses or other overcurrent protection devices such as
a circuit breaker. Group fuses may be added in the pad-mounted
metal-enclosed capacitor bank in addition to the individual capacitor
fusing if suitable overcurrent protection outside of the pad-mounted
capacitor bank is not available.
Visible-Break Switch
For switched capacitor banks, visible-break switches are available in
three versions:
1. 3-pole, group-operated disconnect switch
1. 3-pole, group-operated disconnect switch and 3-pole ground
switch (both switches operated with the same manual operator)
1. 3-pole, group-operated disconnect switch and 4-pole ground
switch (both switches operated with the same manual operator)
The switches are operated from the side of the unit and are
interlocked with the capacitor switches and the access doors. The
230-55-4
www.cooperpower.com
continuous current rating of the visible-break switch is at least 1.5
times the nominal current of the capacitor and the standard rated
1 second short time current is 20 kA (sym). The switch contact
positions are visible via the clear polycarbonate barrier in the
equipment front section. If visible break switches are selected, red
GPO-3 barriers are not optional.
Control Power Transformer
Control power may be supplied by the customer or by an optional
control power transformer (CPT) with a 120 V secondary. Options
include an oil-insulated CPT with an internal weak-link and an
external fuse or a dry-type CPT with an external fuse. In order to
maintain control power in the event of a group fuse operation, the
CPT will be fused separately and connected to the source side of
any group fuses (see Figure 3). The CPT may be used for sensing
voltage for the capacitor control. If the bank is connected grounded
wye, the CPT will be connected line-to-ground. If the bank is
connected ungrounded wye or delta, the CPT will be connected lineto-line.
Capacitor Switches
Four standard options for capacitor switches are offered as follows:
1. Single-phase, oil-interruption switch (Eaton's Cooper Power
Systems Type NR oil switch)
2. Single-phase, vacuum-interruption switch (Eaton's Cooper Power
Systems Edison™ capacitor switch)
3. Three-phase, vacuum-interruption switch (Eaton's Cooper Power
Systems Type VCS-3)
4. Three-phase, vacuum contactor Rated voltage ≤ 6,900 V
For frequent switching, switching devices with vacuum interruption
are recommended. Contact the factory if the bank will be switched
back-to-back with another capacitor bank so we may size the
switching device and any necessary reactors.
Surge Arresters
Surge arresters are optional on the pad-mounted capacitor bank.
The standard offering is either an Eaton's Cooper Power Systems
UltraSIL™ Polymer-Housed VariSTAR™ or an UltraSIL PolymerHoused Evolution™ surge arrester. The arresters are electrically
connected to the internal connection of the bushing well or bushing
for the deadfront option or at the incoming NEMA® terminal for the
livefront option.
An optional Eaton's Cooper Power Systems Storm Trapper™
secondary surge arrester is also available to protect the secondary
circuit.
Capacitor Control
A capacitor control or provisions for a control (optional) may be
installed either inside or outside of the enclosure. On the outside of
the enclosure, the mounting will be on a customer specified meter
socket. On the inside of the enclosure, the control can be surface
mounted or meter socket mounted. If mounted inside the enclosure,
it will be located in the equipment front section.
For single step banks, the standard option for the capacitor control is
the Eaton's Cooper Power Systems CBC-8000 Series capacitor bank
Control.

General
Cooper Power Systems offers the Type NR Oil
Switch for switching inductive and capacitor
currents, to meet the requirements of a wide
range of applications. This switch is an electrically
operated, single-phase switch. The switch also
includes an operating handle for switch position
indication or manual operation. The normal
operation of this switch is managed with an
electric motor requiring low-voltage input. Cooper
Power Systems offers two options for the electric
motor, either 120 Vac, 60 Hz or 240 Vac, 60 Hz.
The switch operation can be managed remotely,
via electrical or electronic controls, or manually at
the installation site when needed.

Description
The Type NR oil switch is a single-phase device for use on
distribution circuits. Compact design makes these switches ideal
for use on capacitor banks, especially pole-top installations. These
switches are electrically operated and can be controlled by various
electrical or electronic devices. An operating handle, which also
serves as a contact position indicator, is provided for manually
opening and closing the switch.
Note: The Type NR oil switch may not be manually closed into a faulted line.
The making current rating to these switches applies to electrical operation
only.
Capacitor bank switching
The standard Type NR single-phase oil switch is rated at 15.0 kV / 95
kV BIL and is capable of switching three-phase capacitor banks up to
3600 kVAR on 14.4 kV systems; with three (3) switches controlled
by customer. Choosing the 125 kV BIL option enables switching
solidly grounded capacitor banks up to 6400 kVAR on multigrounded
wye systems up to 14.4 / 24.9 kV; with three (3) switches controlled
by customer.
The 22.0 kV / 125 kV BIL version of the Type NR oil switch can switch
solidly grounded three-phase capacitor banks up to 2700 kVAR on
20 / 34.5 kV multigrounded-wye systems; with three (3) switches
controlled by customer.

Operation
With switch contacts closed, selecting the "OPEN SWITCH", or
similar, position in the switch controls energizes the switch open
contacts on the electric motor. Through a gear and lever system, this
releases a toggle which allows pre-loaded opening springs to snap
open the switch contacts; loads a heavy spring in preparation for a
closing operation; positions selector switch contacts so that only
the closing circuit can subsequently be energized; and interrupts the
electric motor operating current when the first three functions have
been completed. The opening circuit must remain energized for 4.0
seconds.
Similarly, selecting the "CLOSE SWITCH", or similar, position in the
switch controls energizes the switch close contacts on the electric
motor. This releases the closing spring to close switch contacts and
load opening springs; positions selector switch contacts for the
subsequent opening signal, then interrupts the operating electric
motor current. The closing circuit must remain energized for 0.5
seconds.

Metal-enclosed capacitor banks
General
Metal-enclosed capacitor banks feature the latest
capacitor technology from Eaton's Cooper Power
Systems based on over 70 years of experience in
design and manufacture of power capacitors. The
capacitor banks are designed to meet or exceed
all applicable ANSI®, IEEE®, NEMA®, NEC®,
and IEC® standards. Metal-enclosed capacitor
banks from Eaton's Cooper Power Systems
are engineered-to-order to meet customer
system requirements and indoor or outdoor
site conditions. Metal-enclosed banks are fully
assembled and tested which significantly reduces
site installation costs and time. Custom designs
are available for utility, commercial, and industrial
applications globally. The banks can be designed
to the requirements of IEEE Std 693™-2005 for
seismic conditions.
Metal-enclosed capacitor banks–the sustainable
solution–improve efficiency in the power system
by reducing losses from point of application to
the generator, saving money and decreasing CO2
emissions. Capacitor banks also improve power
quality by supporting voltage and mitigating
harmonic issues–when applied as harmonic filters.
Metal-enclosed banks are typically* offered in the
following ratings:
• 2.4 kV to 38.0 kV
• -50 °C to +55 °C (-58 °F to +131 °F)
• Up to 200 kV BIL
• Up to 63 kA (sym)
Metal-enclosed designs are available as singlestep, multi-stepped, de-tuned, and with harmonic
filtering. Compared to traditional open rack
substation designs, metal-enclosed banks can
provide the same benefit but within a smaller
footprint.
*Consult factory for special ratings or design considerations
not included above.

CLEANBREAK™ element fusing system
Construction features of Eaton's Cooper Power Systems power
capacitors include:
• Mechanical crimping connection system (exclusive to Eaton's
Cooper Power Systems). Provides solderless internal connections
that eliminate localized heating and cold solder joints.
• Stainless steel tank with light gray finish for resistance to
severely corrosive atmospheres. Tank is finished with an epoxy
primer and a urethane topcoat coating system. This system has
been tested to IEEE Std C57.12.31™-2010 and the IEEE Std
C57.12.29™-2005 standards.
• Light-gray, porcelain bushings are blazed for high strength and
durability and hermetically sealed to the capacitor tank.
Protection and control
Protection and control requirements are often unique to each
customer and application. Eaton's Cooper Power Systems can
provide complete protection and control systems designed to
operate independently and/or integrate with the customer’s
protection and control scheme. Control panels can be integrated
as part of the bank enclosure or provided separately for mounting
inside a remote control room.
Intelligent automatic capacitor step controllers can be provided
to select which steps to switch on or off to optimize system
performance. Controllers can be provided to switch manually,

• Supervisory Control and Data Acquisition (SCADA)
• Annunciation panel
• Fusing with blown fuse detection
• Coordination with upstream protective devices
• Safety interlocking
• Temperature, humidity, and condensation control
• Timers and auxiliary equipment
Installation, maintenance and reliability
Metal-enclosed banks are fully assembled and tested at the
factory before delivery to the site. Compared to typical open air
racks the site preparation, engineering time, installation time, and
commissioning time can be greatly reduced.
The banks are low profile and easily accessible to field maintenance
crews. Performing routine maintenance is easier since heavy
equipment is not required to maintain the banks and crews can
access equipment from the ground.
Metal-enclosed banks are commonly used in areas where wildlife
related outages is a concern, in highly corrosive or contaminated site
locations or when environmental conditions are an issue. Depending
on the degree of protection specified the metal enclosure can offer
protection for electrical equipment from these potential hazards
which increase reliability.
Harmonic filters
In locations where harmonic producing loads are a concern
metal-enclosed de-tuning or harmonic filter banks are becoming
a preferred solution due to the reduced installation time and
significant space savings compared to traditional open rack filters.
Air core reactors are commonly used to mitigate back-to-back
switching transients; however when rated for tuning, air core
reactors can require large magnetic field clearances which can
greatly increase the size of the enclosure.
As an alternative, iron core reactors can be used in place of air core
reactors due to the high permeability of the iron core which confines
the magnetic field.
Multiple-step capacitor banks
Metal-enclosed banks can be provided as a single-step or with
multiple steps for optimal flexibility. Electric systems often
need versatile solutions to meet the demands of the system's
requirements. Utilizing multi-step banks offer flexibility and significant
space savings. Multi-step banks using different rated var steps offer
even more versatility due to the different var stage combinations
available.
