RMU IS A DISTRIBUTION SUBSTATION.IT PROVIDES MEDIUM VOLTAGE
POWER SUPPLY 11KV 13.8KV 22KV 33KVS.TWO CIRCUITS PROVIDED
FOR FEEDIND ALTERNATIVELY & ONE FOR TO FEED THE TRANSFORMER
EQUIPED WITH OVER CURRENT AS WELL AS EARTH FAULT PROTECTION
RELAYS TO PROTECT THE TRANSFORMER.I HIGHLY RECMEND THAT TWO
FEEDERS SHOULD BE INTERLOCKED TO AVOID THE OPERATION
SIMELTANEOUSLY.
