Over current relay(O.C.R)) is perated on overload and short circuit. This relay has two elements: one is definitive element for operating and indicating on fault of overload. the other is instantaneous element for operating and indicating in rush current on fault of short circuit. And then this relay is designed that. it is easy to detect a reason of fault and toresponse to what fault is some trouble DCG/DOG type ground over current relay is induction rotary disk type that is operated in remained circuit current of current transformer
