Abstract :
Protection system is important when operating electricity system, especially for reliable dan to protect electric utility. Relay use to protect electric utility and mostly used in electric system. In feeder distribution mostly happen fault to become short circuit, because of that problem in feeder distribution using relay and connect it to the circuit breaker to clear the short circuit current by isolate the feeder from fault. OCR and GFR Relay used most commonly because simple and reliable in electricity operating system. In this study will show the OCR and GFR coordination protection in Hilbron feeder 20 kV between main substation and switch substation Mataram area. The solution is to calculate the value short circuit,time multiple setting,and relay setting. From the calculation,Time Multiple Setting (TMS) for OCR in R1 PMCB Malimbu 0,12, TMS for R2 Recloser Klui 0,14, TMS R3 Hilbron feeder 0,21, TMS R4 Sheraton feeder 0,3 and TMS R5 Trafo Incoming 0,32.Calculation result TMS for GFR in R1 PMCB Malimbu 0,1, TMS R2 Recloser Klui 0,2, TMS R3 Hilbron Feeder 0,31, TMS R4 Sheraton Feeder 0,41 and TMS R5 Trafo Incoming 0,52.
