Abstract :
Coordination of the Over Current Relay (OCR) and Ground Fault Relay (GFR) protection systems which are placed on the incoming section of the 150 kV GI Angke power transformer and on the outgoing section of the 20 kV Bandengan feeder. 13366,13 A, so that the OCR on the outgoing part will work 0.7 seconds, and the incoming OCR will work 0.639 seconds. Meanwhile, the biggest disturbance in 1 phase to ground is 955.69 A. And the relay that will work securely is the outgoing GFR with a working time of 0.688 seconds, while the incoming GFR as a backup will work with a time of 0.6755 seconds. Protective devices are needed to reduce and prevent the impact of short-circuit faults, if the protective equipment is incorrect in responding, a trip can occur. Coordination of OCR and Ground GFR protection placed on pomfret feeders has the aim of preventing a total blackout in the event of a disturbance in the form of short circuit fault current and over current disturbance.
