Electrical energy is channeled using a variety of conducting conductors. usually in the form of a bare conductor free in the air until it reaches the consumer. The disturbance is caused by the presence of an overcurrent in the conductor so that the disturbance occurs and the electric current is cut off to the load. The improvement of the quality of the energy quality that is distributed is very much maintained by the PLN. By reducing the length of outage and the number of times the feeder outages are noticed. In overcoming the occurrence of these disturbances, protection equipment used in the medium network is installed in the form of OCR (over current relay), GFR and recloser. OCR acts as a safety for detecting overcurrent, while GFR is for detecting single-phase faults to ground. To instruct PMT to open. In writing this final project, it discusses the analysis of good relay coordination settings, about recloser working time, OCR and GFR relays in each section. Simulation results in the 1% front of the Gh Recloser detected a large fault current of 1.974 kA, while in one phase to the ground it was 0.255 kA. The PMT disconnect time is 10s. TMS Rec. 0.15s, TMS GFR 0.14s. TMS OCR Outgoing. 0.20s. TMS GFR Outgoing 0.24s. and TMS OCR Incoming 0.21s. TMS GFR 0.35s. it can be concluded that the coordination of the SPINX feeder is quite good.} }
