To reduce the interference needed a protection system that meets the requirements of sensitivity, reliability, selectivity and speed, which all depend on the protection equipment settings. One of the protective equipment used is over current relay (OCR) and ground fault relay (GFR). In writing this research, the OCR and GFR settings for incoming and outgoing settings in the Bay of Substation Bay Betung feeders will be discussed. The results of the calculation of the OCR setting on the incoming side can be TMS value = 0.17, while the OCR setting on the outgoing side is obtained TMS value = 0.18. Setting the GFR on the incoming side to TMS value = 0.23, while the GFR setting on the outgoing side obtained TMS value = 0.11.} }
