23 September 0 Sheet 00 Metal-Clad SwtchgearVacClad-WMedum Voltage Partal Dscharge General Descrpton.- Partal Dscharge Sensng and Montorng for Swtchgear InsulGard Relay Partal Dscharge Equpment 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 that 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. RFCT Sensor Sensng and Montorng Eaton s 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 buffng of all sharp copper edges at the jonts, employng star washers for boltng metal barrers, and usng 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 that 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. InsulGard Relay (PD Montorng) Partal dscharges wthn the swtchgear compartment are detected by nstallaton of a small donut type rado frequency current transformer (RFCT) sensor over floatng stress shelds of the specally desgned bus or lne sde prmary bushngs. Partal dscharges n customer s power cables (external dscharges) are detected by nstallaton of the RFCT around ground shelds of the ncomng or outgong power cables termnaton. In kv swtchgear (refer to Fgure.-), one RFCT sensor s nstalled around prmary bushng stress sheld n every breaker compartment and suppled as standard for measurement of dscharges nternal to the swtchgear compartment. Its output s wred to termnal blocks n control compartment for easy access for perodc feld measurements. It can also be connected drectly to optonal InsulGard relay for contnuous montorng of partal dscharges. Because one RFCT sensor s ncluded n kv breaker compartment, Eaton s kv swtchgear s PD Sensng Ready when receved by the customer. An addtonal RFCT sensor for each ncomng and outgong power cable crcuts can be provded as an opton for measurement of external dscharges. In // kv swtchgear (refer to Fgure.-), prmary epoxy bushngs wth stress sheld and RFCT sensors for measurement of nternal as well as external partal dscharges are all optonal. InsulGard relay s also optonal. When specfed, one set of prmary epoxy bushngs (located on bus sde) wth stress sheld and assocated RFCT sensor s provded at every two vertcal sectons. An addtonal RFCT sensor for each ncomng and outgong power cable crcuts can be provded as requred. The RFCT output sgnals can be connected drectly to InsulGard relay for contnuous montorng of partal dscharges or can be used for perodc feld measurements. 0 0 CA0000E For more nformaton, vst:

Ths was done because nterruptng capabltes of today s vacuum crcut breakers are better represented by K =.0. Unlke old ar-magnetc and ol crcut breakers, today s vacuum 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 toward 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 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 worldwde, 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 the user can select the most economcal crcut breaker that can satsfy ther crcut swtchng applcaton.

Specally rated generator breakers typcally should be used on generator applcatons 0,000 kw and above A generator crcut breaker, properly rated and tested to the approprate ndustry standard, can protect the generator from damage, or even complete falure, that could occur when feedng a faulted transformer, and also can protect the transformer, n the event that a fault should occur n the generator Generator crcuts have unque characterstcs that requre specally desgned and tested crcut breakers. The IEEE developed the specal ndustry standard C.0 and amendment C.0a-00 to address these characterstcs. Eaton Corporaton has dedcated years of research, desgn, enhancement and testng to create Eaton s famly of generator breakers. The VCP-WG (drawout) and VCP-WRG (fxed) crcut breakers meet, and even exceed, the rgorous servce duty requrements for generator crcut applcatons as defned by IEEE. Eaton s VCP-WG and VCP-WRG generator breakers are avalable n two frame szes. The.00-nch frame (.00 nches wde wth front cover on) has ratngs up to kv, ka and 000A (000A wth forced-ar coolng). The.00-nch frame (.00 nches wde wth front cover on) has ratngs up to kv, ka and 000A (000A wth forced-ar coolng). The.00- nch frame s also avalable n a fxed verson wth ratngs up to kv, ka and 000A (000A wth forcedar coolng). Count on Eaton s nnovatve technology to handle hgh contnuous AC current and voltage, then safely swtch through extreme out-of-phase voltages and hgh-stress asymmetrcal currents usng clean and green vacuum nterrupton wthout fal for over 0,000 normal operatons. Eaton s VCP-WG generator crcut breakers meet the strct servce duty requrements set forth by IEEE for generator crcut applcatons, ncludng: Generator crcut confguraton Hgh contnuous current levels Unque fault current condtons Transformer-fed faults Generator-fed faults Unque voltage condtons Very fast RRRV Out-of-phase swtchng Generator Crcut Confguraton The transformer and generator can be n close proxmty to the crcut breaker. See Fgure.-. Applcatons wth hgh contnuous current levels requre connectons wth large conductors of very low mpedance. Ths constructon causes unque fault current and voltage condtons as shown n Fgure.-. ~ Generator Generator Crcut a b Step-up Transformer Hgh Voltage Crcut Fgure.-. Generator Crcut Applcaton Hgh Contnuous Current Levels Generator crcut breakers must be able to handle hgh contnuous current levels wthout overheatng. VCP-WG drawout crcut breakers are desgned to relably operate up to 000A wth natural ar convecton coolng, and up to 000A wth sutable enclosure fan coolng durng overload condtons. VCP-WRG fxed crcut breakers are desgned to relably operate up to 000A wth natural ar convecton coolng and up to 000A wth sutable enclosure fan coolng durng overload condtons. Unque Fault Current Condtons System-source (aka, transformer-fed) faults (see Fgure.-, fault locaton a ) can be extremely hgh. The full energy of the power system feeds the fault, and the low mpedance of the fault current path does very lttle to lmt the fault current. Eaton s type VCP-WG Generator Crcut s are deal for nterruptng such hgh fault currents because they have demonstrated hgh nterrupton ratngs up to ka, wth hgh DC fault content up to %, as proven by hgh power laboratory tests. Generator-source (aka, generator-fed) faults, see Fgure.-, fault locaton b ) can cause a severe condton called Delayed Current Zero, see Fgure.-). The hgh rato of nductve reactance to resstance (X/R rato) of the system can cause the DC component of the fault current to exceed 00%. The asymmetrcal fault current peak becomes hgh enough and ts decay becomes slow enough that the natural current zero s delayed for several cycles. The crcut breaker experences longer arcng tme and more electrcal, thermal and mechancal stress durng the nterrupton. The IEEE standard requres verfcaton that the crcut breaker can nterrupt under these severe condtons. Eaton s VCP-WG generator crcut breakers have demonstrated ther ablty to nterrupt three-phase fault current levels up to % DC content under delayed current zero condtons.

35 September 0 Sheet 00 Unque Voltage Condtons Generator crcuts typcally produce very fast rates of rse of recovery voltage (RRRV) due to the hgh natural frequency and low mpedance and very low stray capactance. VCP-WG generator crcut breakers are desgned to nterrupt fault current levels wth very fast RRRV n accordance wth IEEE standard C.0 and C.0a. VCP-WG generator crcut breakers have a dstnct ablty to perform under out-of-phase condtons when the generator and power system voltages are not n sync.

The dstrbuton system can be subject to voltage transents caused by lghtng or swtchng surges. Recognzng that dstrbuton system can be subject to voltage transents caused by lghtng or swtchng, the ndustry has developed standards to provde gudelnes for surge protecton of electrcal equpment. Those gudelnes should be used n desgn and protecton of electrcal dstrbuton systems ndependent of the crcut breaker nterruptng medum. The ndustry 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. Standards for Metal-Clad Swtchgear Eaton s medum voltage metal-clad and metal-enclosed swtchgear that uses vacuum crcut breakers s appled over a broad range of crcuts. It s one of the many types of equpment n the total dstrbuton system. Whenever a swtchng devce s opened or closed, certan nteractons of the power system elements wth the swtchng devce can cause hgh frequency voltage transents n the system. Due to the wde range of applcatons and varety of ratngs used for dfferent elements n the power systems, a gven crcut may or may not requre surge protecton. Therefore, Eaton does not nclude surge protecton as standard wth ts metal-clad or metal-enclosed medum voltage swtchgear. The user exercses the optons as to the type and extent of the surge protecton necessary dependng on the ndvdual crcut characterstcs and cost consderatons. The followng are Eaton s recommendatons for surge protecton of medum voltage equpment. Please note these recommendatons are vald when usng Eaton s vacuum breakers only. Surge Protecton Recommendatons: Note: The abbrevaton ZORC used n the text below refers to Surge Protecton Devce manufactured by Strke Technology (Pty) Ltd. An equvalent devce offered by other manufacturers, such as Type EHZ by ABB, and Protec Z by Northern Technologes SA can also be used.. For crcuts exposed to lghtnng, surge arresters should be appled n lne wth Industry standard practces.. Transformers a. Close-Coupled to medum voltage prmary breaker: Provde transents surge protecton, such as Surge Arrester n parallel wth RC Snubber, or ZORC. The surge protecton devce selected should be located and connected at the transformer prmary termnals or t can be located nsde the swtchgear and connected on the transformer sde of the prmary breaker. b. Cable-Connected to medum voltage prmary breaker: Provde transent surge protecton, such as Surge Arrester n parallel wth RC Snubber, or ZORC for transformers connected by cables wth lengths up to feet. The surge protecton devce should be located and connected at the transformer termnals. No surge protecton s needed for transformers wth lghtnng mpulse wthstand ratngs equal to that of the swtchgear and connected to the swtchgear by cables at least feet or longer. For transformers wth lower BIL, provde surge arrester n parallel wth RC Snubber or ZORC. RC Snubber and/or ZORC damp nternal transformer resonance: The natural frequency of transformer wndngs can under some crcumstances be excted to resonate. Transformer wndngs n resonance can produce elevated nternal voltages that produce nsulaton damage or falure. An RC Snubber or a ZORC appled at the transformer termnals as ndcated above can damp nternal wndng resonance and prevent the producton of damagng elevated nternal voltages. Ths s typcally requred where rectfers, UPS or smlar electronc equpment s on the transformer secondary.. Arc-Furnace Transformers Provde Surge Arrester n parallel wth RC Snubber, or ZORC at the transformer termnals.. MotorsProvde Surge Arrester n parallel wth RC Snubber, or ZORC at the motor termnals. For those motors usng VFDs, surge protecton should be appled and precede the VFD devces as well.. GeneratorsProvde staton class Surge Arrester n parallel wth RC Snubber, or ZORC at the generator termnals.. Capactor SwtchngNo surge protecton s requred. Make sure that the capactor s lghtnng mpulse wthstand ratng s equal to that of the swtchgear.. Shunt Reactor Swtchng Provde Surge Arrester n parallel wth RC Snubber, or ZORC at the reactor termnals..

44 .- Metal-Clad SwtchgearVacClad-WMedum Voltage Drawout Vacuum s Techncal DataSurge Protecton September 0 Sheet Types of Surge Protecton Devces Fgure.-. Surge Protecton Devces Generally surge protectve devces should be located as closely as possble to the crcut component(s) that requre protecton from the transents, and connected drectly to the termnals of the component wth conductors that are as short and flat as possble to mnmze the nductance. It s also mportant that surge protecton devces should be properly grounded for effectvely shuntng hgh frequency transents to ground. 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 surge arrester. Notce that publshed arrester MCOV (Maxmum Contnuous Operatng Voltage) ratngs are based on 0º or ºC ambent temperature. In general, the followng gudelnes are recommended for arrester selectons, when nstalled nsde Eaton s medum voltage swtchgear: A. Soldly Grounded Systems: 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 ºC 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 Resstant Grounded Systems (systems grounded through resstor rated for 0 seconds): Arrester 0-second MCOV capablty at 0ºC, whch s obtaned from manufacturer s data, should be equal to.0 x 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 or Systems Grounded through mpedance other than 0-second resstor: Arrester MCOV ratng should be equal to.0 x V LL /T, where V LL and T are as defned above. Refer to Table.- for recommended ratngs for metal-oxde surge arresters that are szed n accordance wth the above gudelnes, when located n Eaton s 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 surge 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 and. kv, 0. µf on kv, and 0. µf on systems operatng at kv and hgher. RC Snubber A RC Snubber devce conssts of a non-nductve resstor R szed to match surge mpedance of the load cables, typcally 0 to 0 ohms, and connected n seres wth a Surge Capactor C. The Surge Capactor s typcally szed to be 0. to 0. mcrofarad. Under normal operatng condtons, mpedance of the capactor s very hgh, effectvely solatng the resstor R from the system at normal power frequences, and mnmzng heat dsspaton durng normal operaton. Under hgh frequency transent condtons, the capactor offers very low mpedance, thus effectvely nsertng the resstor R n the power system as cable termnatng resstor, thus mnmzng reflecton of the steep wave-fronts of the voltage transents and prevents voltage doublng of the travelng wave. The RC Snubber provdes protecton aganst hgh frequency transents by absorbng and dampng and the transents. Please note RC Snubber s most effectve n mtgatng fast-rsng transent voltages, and n attenuatng reflectons and resonances before they have a chance to buld up, but does not lmt the peak magntude of the transent. Therefore, the RC Snubber alone may not provde adequate protecton. To lmt peak magntude of the transent, applcaton of surge arrester should also be consdered. ZORC A ZORC devce conssts of parallel combnaton of Resstor (R) and Znc Oxde Voltage Suppressor (ZnO), connected n seres wth a Surge Capactor. The resstor R s szed to match surge mpedance of the load cables, typcally 0 to 0 ohms. The ZnO s a gapless metal-oxde non-lnear arrester, set to trgger at to PU voltage, where PU =.*(V L-L /.). The Surge Capactor s typcally szed to be 0. to 0. mcrofarad. As wth RC Snubber, under normal operatng condtons, mpedance of the capactor s very hgh, effectvely solatng the resstor R and ZnO from the system at normal power frequences, and mnmzng heat dsspaton durng normal operaton. Under hgh frequency transent condtons, the capactor offers very low mpedance, thus effectvely nsertng the resstor R and ZnO n the power system as cable termnatng network, thus mnmzng reflecton of the steep wave-fronts of the voltage transents and prevents voltage doublng of the travelng wave. The ZnO element lmts the peak voltage magntudes. The combned effects of R, ZnO, and Capactor of the ZORC devce provdes optmum protecton aganst hgh frequency transents by absorbng, dampng, and by lmtng the peak ampltude of the voltage wave-fronts. Please note that the ZORC s not a lghtnng protecton devce. If lghtnng can occur or be nduced n the electrcal system, a properly rated and appled surge arrester must precede the ZORC.

46 .-0 Metal-Clad SwtchgearVacClad-WMedum Voltage Drawout Vacuum s Techncal DataSurge Protecton and Instrument Transformers September 0 Sheet 00 0 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 A and/or 0V, 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. When two VTs are used, they are typcally connected L-L, and provde phase-to-phase voltages, (Vab, Vbc, Vca) for meterng and relayng. When three VTs are used, they are connected lne-to-ground, and provde phase-to-phase (Vab, Vbc, Vca), as well as phase-to-ground (Va, Vb, Vc) voltages for meterng and relayng. If meterng or relayng applcaton requres phase-to-ground voltages, use three VTs, each connected L-G. If not, use of two VTs connected L-L s suffcent. For ground detecton, three VTs connected n Lne-to-ground/brokendelta are used. A sngle VT, when used, can be connected lne-to-lne (t wll provde lne-to-lne output, for example Vab or Vbc or Vca), or lne-to-ground (t wll provde lne-to-ground output, for example Va or Vb or Vc). Generally, a sngle VT s used to derve voltage sgnal for synchronzng or Over Voltage/Under Voltage functon. Current Transformers The current transformer rato s generally selected so that the maxmum load current wll read about 0% full scale on a standard A 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 because 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 00/ 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 two-phase connected current transformers and one zero-sequence current transformer. Separate sets of current transformers are requred for dfferental relays. The mnmum pckup of a ground relay n the resdual of three-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.- for CT accuracy nformaton. Table.-.
