•
High stacking factor design (exclusive to Eaton) utilizing aluminum
foil electrodes with a laser-cut or folded active edge. The region
of the dielectric exposed to the highest electric field stress is
located at the active edge of the electrode. The high stacking
factor and laser-cut / folded active edge shapes and reduces the
electric field stress thereby significantly increasing the discharge
inception voltage (DIV). Eaton's capacitors are designed to have
the highest safety margin to DIV in the industry.

Metal-enclosed, pad-mounted capacitor banks
Effective August 2015
Bank connection
The capacitors may be configured as follows:
•
Grounded wye
•
Ungrounded wye
•
Delta
Control power transformer
Please see the Fusing section and the selection tables for available
ratings.
Fusing
Each pad-mounted capacitor bank comes standard with currentlimiting fuses for fusing the capacitors. Group fusing and/or
individual capacitor fusing are available for most ratings.
Group fusing is standard for all grounded wye banks where available
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 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
continuous current rating of the visible-break switch is at least 1.5
4
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.
www.eaton.com/cooperpowerseries
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
series Type NR oil switch)
2. Single-phase, vacuum-interruption switch (Eaton's Cooper Power
series Edison® capacitor switch)
3. Three-phase, vacuum-interruption switch (Eaton's Cooper Power
series Type VCS-3 vacuum switch)
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 series
UltraSIL® Polymer-Housed VariSTAR® or an UltraSIL Polymer-Housed
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 series 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
Eaton's Cooper Power series CBC-8000 capacitor bank control.
