Abstract :
Electric power is one of the basic needs at this time. At the time of distribution of electrical energy does not always flow perfectly, sometimes there is interference, one of these disturbances is a short circuit. With the interference, one of the equipment that can secure is the relay. Over current relay (OCR) is one of the relays that can secure short circuit between phases that occur. Therefore it is set correctly so as to minimize the occurrence of damage to other devices. This final project discusses the adjustment of overcurrent relays on 20kV Gunawan feeders in Grogol Insulated Swithchgear Gas. Relay adjustment is obtained with the largest current value in the 3 phase short circuit fault current which is 12620.08 A with a setting time of 0.49 seconds. With these results can be used to adjust the relay current more see the results of the time it can.
