NPSC800 & NPSC800R / NPSC800RE – Network Check Synchronizing Relay
Products family : Synchro-Check Relay
Sector : Generation, Industry
NPSC800-1 & NPSC800R perform check of synchronism between two power supplies. They are usually used to authorize the closing order of a paralleling circuit breaker.
NPSC800-2 & NPSC800RE allow in addition the operating of live (or dead) line and live (or dead) bus. They also allow, with a dedicated output relay, the reconnection of two bus sections fed by the same supply.
NPSC800R (R2 case) & NPSC800RE (R3 case) is dedicated to the refurbishment of CEE STS 7041 relay (R3 case).
Two mountings are available, Flush Rear Connection (EDPAR) or Projecting Rear Connection (SDPAR). A blank cover R1, provide in option, can improve mechanical installation (replacement of CEE case R3 by a NPSC800R).
As well as the usual protection functions, NP800 relays provide monitoring, measurement and recording of the electrical quantities of the network.
Setting, reading, measurement and recording are all available locally or remotely.
