Description

Widerangeof applications

The SIPRO TEC 7SJ601 is anum ericalovercurrentrelayw hich,in addition to its prim a-ry use in radialdistribution pow -ersystem s and m otorpro-tection,can also be em ployedas backup forline,transform erand generatordifferentialpro-tection.

Itprovides definite-tim e and in-verse-tim e overcurrentprotec-tion.

Construction

The device contains allthecom ponents needed for

• acquisition and evaluation ofm easured values

• operation and display (localM M I)

• outputofsignals and tripcom m ands

• inputand evaluation ofbinarysignal

• auxiliary voltage supply

The nom inalC T currents ap-plied to the SIPRO TEC 7SJ601can be 1 A or5 A.

Tw o differentcases areavailable.The flush-m ountingorcubicle version has term i-nals atthe rear.The surface-m ounting version has term i-nals atthe front.

Improvedmeasurementtechnique

The SIPRO TEC 7SJ601 relayoperates fully num ericalw ithenhanced algorithm s.D ue tothe num ericalprocessing ofm easured values,the influ-ence ofhigher-frequency tran-sientphenom ena and tran-sientD C com ponents islargely suppressed.

Continuous self-monitoring

The hardw are and softw are inthe SIPRO TEC 7SJ601 deviceare continuously self-m onito-red.This ensures a very highlevelofavailability and reducesthe need forroutine testing.

Convenient setting

The m enu driven H M Iis usedforsetting param eters.These

param eters are stored in a non-volatile m em ory so thatthesettings are retained even ifthe supply voltage is cutoff.

Circuit-breaker / Tripcon-tacttesting

The trip and reclose com m andcontacts can be activated viathe keyboard.This facilitatestesting ofthe trip and close cir-cuits w ithoutthe need foraddi-tionaltestequipm ent.

Statusof inputsand outputs

Foreasy com m issioning thestatus ofeach binary input,re-lay orLE D can be displayed viaH M I.

Event loggingwithtimestamp

The SIPRO TEC 7SJ601 devicesupplies detailed data fortheanalysis offaults and forcheck-ing on operating conditions.

• EventlogsThe last3 eventlogs can al-w ays be displayed.Ifa new

faultoccurs,the oldestw illbe overw ritten.These logsgive a detailed description ofthe faultin the pow ersys-tem and the reaction oftheSIPRO TEC 7SJ601,w ith1m s resolution. Each recordis tim e stam ped and as-signed a sequentialnum ber.

• O peration indicationsThis log records up to 30 in-ternalevents in the relayw ith 1m s resolution. Theseevents include setting chan-ges and resets to the relay,binary inputactivity and

otherrelay internalactivities.

Definite-timeovercurrentprotection

The definite-tim e overcurrentfunction is based on phase-selective m easurem entofthethree phase currents.

The earth (ground)current I E (G nd)is calculated from thethree line currents I L1 (A ), I L2(B),and I L3 (C).The definite-tim e overcurrentprotection forthe three phasecurrents has a low -setovercur-

rentelem ent( I >)and a high-setovercurrentelem ent( I >>).In-tentionaltrip delays can be pa-ram eterized from 0.00 to 60.00seconds forthe low -setandhigh-setovercurrentelem ents.

Busbar protection(R everse interlocking)

Reverse interlock principle in-volves the blocking ofthe high-speed overcurrentprotectionon the supply feeder,to the aux-iliary bus,ifany ofthe load fee-derovercurrentrelays are inpickup.Ifa faultis notpresenton any ofthe associated loadfeeders,the supply’s high-speed overcurrentprotectionw illnotbe blocked,providingreliable protection forbusfaults.

In this m anner,selective high-speed overcurrentrelaying canbe applied to the supply andload feeders to provide coordi-

nated bus protection.The re-lays,through contactinputandoutputinterconnection,candiscrim inate and operate selec-tively forvarious types offaults and locations,trippingonly the affected parts ofthesystem .
