Communcatons wres can be extended up to,000 feet (,0 m) from the master control unt wthout repeaters...and as many as,000 compatble devces, nstalled n varous assembles, can be on the PowerNet system. Easy Installaton Installaton s uncomplcated and devces are connected, dasy chan style, va the twsted par conductors. All assembles and devces are standard Cutler-Hammer equpment when PowerNet compatble devces are ordered as part of an assembly. The assembles (wth compatble devces bult-n) are prewred, pretested and delvered complete. Flexblty PowerNet s flexble n that t can nclude those assembles, such as VacClad-W swtchgear, that are desred n a dstrbuton system...but PowerNet can be easly upgraded as new assembles are added. In essence, a customer determnes the requrements for a buldng s electrcal dstrbuton system, and Eaton provdes the PowerNet system to ft those specfc requrements.

13 January 00 Sheet 0 General Descrpton Partal Dscharge Sensng and Montorng.0- Partal Dscharge Sensng and Montorng for Swtchgear InsulGard Relay Partal Dscharge n Swtchgear Partal dscharge s a common name for varous forms of electrcal dscharges such as corona, surface trackng, and dscharges nternal to the nsulaton. It partally brdges the nsulaton between the conductors. These dscharges are essentally small arcs occurrng n or on the surface of the nsulaton system when voltage stress exceeds a crtcal value. Wth tme, arborne partcles, contamnants and humdty lead to condtons whch result n partal dscharges. Partal dscharges start at a low level and ncrease as more nsulaton becomes deterorated. Examples of partal dscharge n swtchgear are surface trackng across bus nsulaton, or dscharges n the ar gap between the bus and a support, such as where a bus passes through an nsulatng wndow between the sectons of the swtchgear. If partal dscharge process s not detected and corrected, t can develop nto a full-scale nsulaton falure followed by an electrcal fault. Most swtchgear flashover and bus falures are a result of nsulaton degradaton caused by varous forms of partal dscharges. Sensng and Montorng Eaton s Cutler-Hammer Type VCP-W metal-clad swtchgear (. kv) s corona-free by desgn. Corona emssons wthn the standard VacClad swtchgear assembles have been elmnated or reduced to very low levels by specal fabrcaton and assembly technques, such as roundng and Partal Dscharge Equpment Couplng Capactor Type PD Sensor RFCT Sensor buffng of all sharp copper edges at the jonts, employng star washers for boltng metal barrers, and utlzng specally crafted standoff nsulators for prmary bus supports. By makng swtchgear assembles corona-free, Eaton has made ts standard swtchgear more relable. However, as ndcated above, wth tme, arborne partcles, contamnants and humdty lead to condtons whch cause partal dscharges to develop n swtchgear operatng at voltages 000V and above. Type VCP-W swtchgear can be equpped wth factory nstalled Partal Dscharge Sensors and Partal Dscharge Sensng relay for contnuous montorng of the partal dscharges under normal operaton. Tmely detecton of nsulaton degradaton through ncreasng partal dscharges can dentfy potental problems so that correctve actons can be planned and mplemented long before permanent deteroraton develops. Partal dscharge detecton can be the foundaton of an effectve predctve mantenance program. Trendng of partal dscharge data over tme allows predcton of falures, whch can be corrected before catastrophc falure occurs. The PD sensng and montorng system conssts of Eaton s InsulGard Relay and PD sensors specfcally developed for applcaton n the swtchgear to work wth the relay. There are two types of PD sensors used n the swtchgear: The frst sensor s a couplng capactor type sensor developed for use wth, and kv swtchgear. InsulGard Relay (PD Montorng) The couplng capactor sensor detects partal dscharges wthn the swtchgear cubcle and/or adjacent cubcles and s typcally nstalled on the load sde of the feeder breakers or on the man bus. The second sensor s a small donut type rado frequency current transformer (RFCT). It s desgned for nstallaton around ground shelds of customer s ncomng or outgong power cables. It detects partal dscharges n customer s power cables and external electrcal nose. RFCT s also used n kv swtchgear for detecton of partal dscharge wthn the cubcle by nstallng t over floatng stress shelds of the bus or lne sde prmary bushngs. In, and kv swtchgear, typcally one set of couplng capactor sensors s used at every two cubcles when nstalled on load sde of the feeder breakers, or at every three cubcles when nstalled on the man bus. One RFCT sensor s used for each ncomng and outgong power cable crcut. Both the couplng capactors and RFCT sensors are optonal n, and kv swtchgear. In kv swtchgear, one RFCT sensor s nstalled around prmary bushng shelds n every breaker compartment and suppled as standard. Its output s wred out to termnal blocks n control compartment for easy access. Each kv breaker compartment s suppled wth ths RFCT sensor as standard, meanng Cutler-Hammer kv swtchgear s PD ready when receved by the customer. The RFCT output sgnal can be fed nto InsulGard Relay for contnuous montorng of PD dscharges or can be used for perod feld measurements by unversal partal dscharge analyzer. An addtonal RFCT sensor for each ncomng and outgong power cable crcuts can be provded as an opton. It can be used wth InsulGard Relay or for feld measurements. CA000E For more nformaton vst:

16 .0- Techncal Data Standard VCP-W Crcut s January 00 Sheet 0 Dscusson of changes n the Rated Voltage Range Factor, K, or K-Factor n Crcut Ratng Structure In and 000 edtons of ANSI C.0, under Table, preferred values for the rated voltage range factor, K, were set to.0 for all ndoor crcut breaker ratngs. Ths was done because nterruptng capabltes of today s crcut breakers are better represented by K =.0. Unlke old ar-magnetc and ol crcut breakers, today s vacuum and SF breakers generally do not requre a reducton n nterruptng current, as the operatng voltage s rased to rated maxmum voltage, for example from. kv up to kv. The nterruptng capablty of vacuum crcut breakers s essentally constant over the entre range of operatng voltages, up to and ncludng ts rated maxmum voltage. The change was also made as a step towards harmonzng preferred ANSI ratngs wth the preferred ratngs of IEC standards. It was further recognzed that t s much smpler to select and apply crcut Crcut Type Nomnal Voltage Class Nomnal -Phase MVA Class Note: Refer to Page.0- for footnotes. breakers rated on the bass of K =.0. The change n the K value, however, n no way affects the ratngs and capabltes of crcut breakers orgnally tested and rated on the bass of K > n the earler edtons of C.0. Exstng crcut breakers, wth ratngs based on K >.0, are stll perfectly vald, meet the latest edtons of the standards, and should be contnued to be appled as they have been n the past. The orgnal K >.0 ratngs are nether obsolete nor nferor to the new K =.0 ratngs; they are just dfferent. The new and 000 edtons of ANSI standard C.0 stll nclude the earler K > ratngs as Table A and AA. The change from K >.0 to K =.0 should be mplemented by manufacturers as they develop and test new crcut breakers desgns. The change does not requre, recommend or suggest that manufactures re-rate and re-test exstng breakers to new standard. And accordngly, Eaton contnues to offer both crcut breakers rated on the tradtonal bass of K >.0 just as thousands of those breakers have been appled for varety of crcut swtchng applcatons world wde, and also as Eaton develops new breakers, they are rated and tested to the new K = ratngs. As a leader n vacuum nterrupton technology, Eaton contnues to provde a wde choce of modern vacuum crcut breakers so that user can select the most economcal crcut breaker that can satsfy hs crcut swtchng applcaton.

20 .0-0 Techncal Data Type VCP-WG Generator Crcut s January 00 Sheet 00 Type VCP-WG Generator Crcut s Why generator crcut breakers? Sufferng a transformer fault s very unfortunate, however, also losng the generator n addton, as a result of ts feedng the transformer fault, would be far worse. Smlarly, losng the transformer as the result of a fault n a generator would be very unfortunate as well. Wth a generator crcut breaker, properly rated and tested to the approprate ndustry standard, one can protect the generator from damage, or even complete falure, that could occur when t would be feedng a faulted transformer, and also one can protect the transformer, n the event that a fault would occur n the generator. Generator crcuts have unque characterstcs that requre crcut breakers specally desgned and tested for these applcatons. Many people are just begnnng to dscover the specal requrements that are assocated wth generator crcuts. The VCP-WG was desgned to meet and exceed the rgorous servce duty requrements of generator crcut applcatons n accordance wth standard C.0-, the IEEE standard for ac Hgh Voltage Generator Crcut s rated on a Symmetrcal Bass. Generator crcuts present unque condtons for the crcut breakers, such as: Hgh contnuous current levels. Hgh fault currents due to exposure to both generator-fed faults and transformer-fed faults. Hgh dc asymmetry. Delayed current zeroes. Hgh close and latch current. Very fast Rate of Rse of Recovery Voltage (RRRV). Out-of-phase swtchng. Generator crcut breakers must be able to carry hgh contnuous currents. The type VCP-WG crcut breaker s desgned to relably operate up to 000 A wth natural ar convecton coolng and up to 00 A wth optonal forced fan coolng durng overload condtons. The VCP-WG crcut breakers are deal for nterruptng transformer-fed faults (fault locaton a n Fgure.0-) up to ka wth up to % dc. ~ Generator Generator Crcut a b Step-up Transformer Hgh Voltage Crcut Fgure.0-. Generator Crcut Applcaton Generator-fed faults (fault locaton b n Fgure.0-) can produce a severe condton called delayed current zero shown n Fgure.0-. The hgh X/R rato along wth other condtons of the generator crcut can cause dc component of the fault current to exceed 0%. Current pu The asymmetrcal fault current peak becomes hgh enough and ts decay becomes slow enough that the frst current zero can be delayed for several cycles. The crcut breaker experences longer arcng tme and more electrcal, thermal, and mechancal stresses durng the nterrupton, than t would see n standard dstrbuton crcuts. The IEEE standard C.0 requres verfcaton that the crcut breaker can nterrupt under these severe condtons.

25 January 00 Sheet 0 Techncal Data Surge Protecton.0- Surge Protecton Eaton s Cutler-Hammer VacClad-W metal-clad swtchgear s appled over a broad range of crcuts, and s one of the many types of equpment n the total system. The dstrbuton system can be subject to voltage transents caused by lghtng or swtchng surges. Recognzng ths phenomenon, the ndustry has developed standards to provde gudelnes for applcaton of electrcal equpment, whch should be used n the desgn of dstrbuton systems ndependent of the breaker nterruptng medum. These standards are: ANSI C Gudes and Standards for Surge Protecton IEEE Buff Book IEEE Recommended Practce for Protecton and Coordnaton of Industral and Commercal Power Systems IEEE Red Book Recommended Practce for Electrc Power Dstrbuton for Industral Plants IEEE C.0. Standard for Metal-Clad Swtchgear In general, f the BIL of the system s equal to the BIL of VacClad-W metal-clad swtchgear, no protecton s requred aganst swtchng surges; however, standard BIL dry-type transformers and rotatng apparatus rarely meet ths crtera. For crcuts exposed to lghtnng, protecton s recommended n lne wth standard practces. In a wde range of applcatons, not all crcuts requre surge protecton. Therefore, VacClad-W metal-clad swtchgear does not nclude any surge protecton as standard. The user exercses the optons as to the type of protecton deemed necessary, dependng on the ndvdual crcut characterstcs and cost consderatons. The followng recommendatons are outlned to provde gudelnes of mnmum surge protecton for metalclad swtchgear and the assocated system equpment:. Lghtnng Provde standard lghtnng protecton.. Swtchng surge protecton: a. Lqud-flled transformer no surge protecton requred. b. Dry-type transformers: kv 0 kv BIL; kv kv BIL; kv kv BIL;. kv kv BIL; kv 0 kv BIL no surge protecton requred. Turn-to-turn nsulaton protecton: Surge capactors may be requred on some systems where a steep rate of rse s expected whch may damage turn-to-turn nsulaton. For all other voltage/bil ratngs for dry-type transformers, surge protecton (arresters or capactors) s recommended at the transformer termnals, n lne wth establshed practces. Metal oxde surge arresters can be suppled n VacClad-W swtchgear as an alternate to above. c. Motors Surge capactors at the motor termnals (and surge arresters where approprate). d. Generators Surge capactors and staton class surge arresters at machne termnals. e. Swtchng overhead lnes and underground cables No surge protecton requred. f. Capactor swtchng No surge protecton requred. g. Shunt reactor swtchng -phase kv dry-type reactors less than MVA requre surge protecton at the reactor s termnals. h. For kv crcuts, refer to Table.0- for Surge Protecton Applcaton Summary. These applcaton gudelnes for VacClad-W metal-clad swtchgear were establshed after extensve analyss of medum voltage power systems. Surge Arresters The modern metal-oxde surge arresters are recommended because ths latest advance n arrester desgn ensures better performance and hgh relablty of surge protecton schemes. Manufacturer s techncal data must be consulted for correct applcaton of a gven type of arrester. Notce that publshed arrester MCOV (maxmum contnuous operatng voltage) ratngs are based on 0 C ambent temperature range. In general, the followng gudelnes are recommended for arrester selectons, when nstalled nsde the VCP-W metal-clad swtchgear: a. Soldly Grounded System Mnmum arrester MCOV ratng should be equal to.0 x V LL / (. x T), where V LL s nomnal lne-to-lne servce voltage,.0 factor allows for +% voltage varaton above the nomnal voltage accordng to ANSI C., and T s deratng factor to allow for operaton at C swtchgear ambent, whch should be obtaned from the arrester manufacturer for the type of arrester under consderaton. Typcal values of T are: 0. to.0. b. Low Resstance Grounded Systems (systems grounded through resstor rated seconds) Arrester -second MCOV capablty at 0 C, whch s obtaned from manufacturer s data, should be equal to.0 V LL, where V LL s nomnal lne-to-lne servce voltage, and.0 factor allows for +% voltage varaton above the nomnal voltage. c. Ungrounded Systems or Systems Grounded through mpedance other than -second resstor The arrester mnmum MCOV ratng should be equal to.0 V LL /T, where V LL and T are as defned above. Refer to Table.0- for recommended ratngs for metal-oxde surge arresters located n metal-clad swtchgear. Surge Capactors Metal-oxde surge arresters lmt the magntude of prospectve surge overvoltage, but are neffectve n controllng ts rate of rse. Specally desgned capactors wth low nternal nductance are used to lmt the rate of rse of ths surge overvoltage to protect turn-to-turn nsulaton. Recommended values for surge capactors are: 0. µf on kv and. kv, 0. µf on kv, and 0. µf on kv and hgher systems. CA000E For more nformaton vst:

For values of C s and R s, see Table.0-. The resstor s mportant to lmt capactve current n the event of a re-gnton. Ths s especally mportant when large power factor correcton-capactor banks are used. Transformer Arc Furnace Man Bus VCP-W Vacuum Crcut R S C S Surge Arrester Fgure.0-. Resstor-Capactor Protecton for Arc Furnaces Instrument Transformers Instrument transformers are used to protect personnel and secondary devces from hgh voltage, and permt use of reasonable nsulaton levels for relays, meters and nstruments. The secondares of standard nstrument transformers are rated at amperes and/or 0 volts, 0 Hz. Voltage Transformers Selecton of the rato for voltage transformers s seldom a queston snce the prmary ratng should be equal to or hgher than the system lne-to-lne voltage. The number of potental transformers per set and ther connecton s determned by the type of system and the relayng and meterng requred. The -phase, -wre system wth -element watthour meters would requres a set of two lne-to-lne voltage transformers. If lne-to-ground potental s also requred for a drectonal ground relay, then a set of three lne-to-ground voltage transformers could be used to provde both lne-to-lne potental for the -element watthour meter and lneto-ground potental for the ground relay. Ground detecton lghts or relays for the ungrounded system requres three lne-to-ground voltage transformers and a separate set s usually recommended for ths purpose. The -phase, -wre, soldly grounded system usually requres three lne-toground voltage transformers for -/- or -element meterng. Where synchronzng of generators or systems s nvolved, t s recommended that only lne-to-lne potental be used. Current Transformers The current transformer rato s generally selected so that the maxmum load current wll read about 0% full scale on a standard -ampere col ammeter. Therefore, the current transformer prmary ratng should be 0 0% of the maxmum load current. Maxmum system fault current can sometmes nfluence the current transformer rato selecton snce the connected secondary devces have publshed one-second ratngs. The zero-sequence current transformer s used for senstve ground fault relayng or self-balancng prmary current type machne dfferental protecton. The zero-sequence current transformer s avalable wth a nomnal rato of 0/ or 0/ and avalable openng sze for power cables of -/ nches (. mm). Specal zero-sequence transformers wth larger wndows are also avalable. The mnmum number of current transformers for crcut relayng and nstruments s three current transformers, one for each phase or -phase connected current transformers and one zero-sequence current transformer. Separate sets of current transformers are requred for dffer-ental relays. The mnmum pckup of a ground relay n the resdual of -phase connected current transformers s prmarly determned by the current transformer rato. The relay pckup can be reduced by addng one resdual connected auxlary current transformer. Ths connecton s very desrable on man ncomng and te crcuts of low resstance grounded crcuts. When utlzng the MP-000 Motor Protectve Relay, t s recommended that the rato of CT prmary ratng to the motor full load amperes (CTprm/Motor FLA) s selected to fall between 0. to.. Standard accuracy current transformers are normally more than adequate for most standard applcatons of mcroprocessor-based protectve relays and meters. See Table.0- for CT accuracy nformaton.

Surge capactor (0. µf) wth seres resstor ( 0 Ohms) appled at each transformer termnal. Sometmes a length of cable between the crcut breaker and the transformer can also mnmze overvoltages. Very fast delectrc strength recovery of VCP-W breakers after nterrupton s a dstnct advantage for swtchng transformer secondary faults, whch produce fast rsng TRVs.

Closng the breaker charges acceleratng sprngs. Protectve relays or the control swtch wll energze a shunt trp col to release the acceleratng sprngs and open the breaker. Ths requres a relable source of control power for the breaker to functon as a protectve devce. Typcal ac and dc control schematcs for type VCP-W crcut breakers are shown on Pages.0- and.0-. For ac control, a capactor trp devce s used wth each crcut breaker shunt trp to ensure that energy wll be avalable for trppng durng fault condtons. A control power transformer s requred on the source sde of each ncomng lne breaker. Closng bus te or bus sectonalzng breakers wll requre automatc transfer of control power. Ths control power transformer may also supply other ac auxlary power requrements for the swtchgear. For dc control, t would requre a dc control battery, battery charger and an ac auxlary power source for the battery charger. The battery provdes a very relable dc control source, snce t s solated from the ac power system by the battery charger. However, the battery wll requre perodc routne mantenance and battery capacty s reduced by low ambent temperature. Any economc comparson of ac and dc control for swtchgear should consder that the ac capactor trp s a statc devce wth neglgble mantenance and long lfe, whle the dc battery wll requre mantenance and replacement at some tme n the future. Relays Mcroprocessor-based or sold-state relays would generally requre dc power or relable unnterruptble ac supply for ther logc crcuts. Auxlary Swtches Optonal crcut breaker and cell auxlary swtches are avalable where needed for nterlockng or control of auxlary devces. Typcal applcatons and operaton are descrbed n Fgure.0- and Table.0-. Auxlary swtch contacts from the crcut breaker mechansm are lmted n number by the breaker control requrements usually to one a and three b contacts for ac control or two a and three b contacts for dc control. When addtonal auxlary contacts are needed, the optonal auxlary relay or mechansm operated cell (MOC) swtch s used.
