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.

Answer / khalid mahmood janjua
RING MAIN UNIT IS TO BE USED TWO INCOMMING AND ONE OUT GOING GENERALLY BUT SOME TIMES ONE INCOMMING AND TWO OUT GOINGS MEDIUM VOLTAGE SUPPLIES.IN ENGINEERING DISTRIBUTION THIS IS CALLED FLEXIBLE POWER SUPPLY.NO A DAY SF6 CIRCUIT BREAKERS GOING TO BE USED.THESE ARE MAINTENANCE FREE BREAKERS.REMEMBER THAT SOLID WITH EPOXY RESIN CAST ALSO USED THOSE ARE NOT LATEST BUT ARE COMPATIBLE TO INTERNAL STANDARDS.
