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 in: • Pole-Mounted racks • Substation banks • Metal enclosures • Mobile Capacitor Banks Designs meeting the requirements of International Electrotechnical Commission (IEC), Canadian Standards Association (CSA), Brazilian Association of Technical Standards (ABNT), and other national and international standards are available. • Improved power factor • System capacity release • Reduced losses • Improved power flow capability • Voltage support Cooper Power Systems all-film, extended foil/ solderless capacitors with a high stacking factor provide: • Harmonic filtering • Low dielectric losses (0.05 watt/kvar) • Surge suppression • Personnel safety through a superior definite tank-rupture characteristic • Low capacitance change with respect to temperature • Tank rupture curves defined through 10 kA for Standard- and Heavy-Duty and 15 kA for Extreme-Duty • Superior electrical performance and reliability • Proprietary Edisol™ VI dielectric fluid that provides the best balance between low and high ambient temperature operation 230-10-1 Technical Data 230-10 Effective March 2014 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 Additional References • Tank rupture curve defined through 10 kA • Standard temperature rating -40 to +55 °C (-50 °C available, consult factory) Refer to the following reference literature for application recommendations. • Meets Performance Test requirements of IEEE Std C18™-2012 standard Table 3 lists the ratings and catalog numbers for the Heavy-Duty single- and double-bushing capacitors. Other unit kvar, voltage, frequency, and BIL ratings are available.

In general, capacitors are installed: • 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. 230-12-2 www.cooperpower.com EX-7Li and EX-7Fi single-phase internally fused capacitor units Technical Data 230-12 Effective June 2014 Table 1.

Technical Data 230-31 Effective June 2014 Supersedes August 2012 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 230-31-1 Technical Data 230-31 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.

Typical fuseless bank schematic. Fuseless capacitor banks Technical Data 230-31 Effective June 2014 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.

Typical pad-mounted capacitor bank equipment rear section. www.cooperpower.com 230-55-3 Technical Data 230-55 Metal-enclosed, pad-mounted capacitor banks Effective June 2014 Bank Connection The capacitors may be configured as follows: • Grounded wye • Ungrounded wye • Delta 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 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.

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. 230-60-1 Technical Data 230-60 Electrically operated Type NR oil switch Effective October 2013 LIFTING STRAP convenient for hoisting entire switch or for lifting mechanism from tank BUSHING TERMINALS accept No. 8 through 2/0 copper or aluminum conductors, either vertically or horizontally BUSHINGS wet-process porcelain with light-gray glaze.

Untanked Type NR oil switch. 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. 230-60-2 www.cooperpower.com Table 1. Summary of Ratings Switch Type NR NRV Application General Purpose Duty Maximum Operating Voltage (kV) Rated Switching Current (A) 15.0 200* 22.0 60 * General purpose duty switches are rated for both capacitive and inductive current switching applications. 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. Electrically operated Type NR oil switch Technical Data 230-60 Effective October 2013 Table 2.

Technical Data 230-70 Effective April 2014 New Issue 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. 230-70-1 Technical Data 230-70 Metal-enclosed capacitor banks Effective April 2014 Metal-enclosed capacitor bank features Eaton's Cooper Power Systems exclusive all-film, extended foil/ mechanically connected capacitors provide: • Low dielectric losses (0.05 watts/kvar) remotely, or automatically on voltage, vars, current, temperature and time control.

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, 230-70-2 www.cooperpower.com • 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. Metal-enclosed capacitor banks Technical Data 230-70 Effective April 2014 Enclosure Ordering information The enclosure is a self-supporting structure manufactured of 12-gauge mild steel (standard). Aluminum 304L and 316L stainless steel are available as options. Structures are typically mounted on a heavy-duty rectangular steel channel base with an open bottom for mounting on a concrete pad.
