The distribution system is part of the electric power system that functions to distribute electricity to consumers, so the operation of the protection system requires reliable protection of distribution equipment from disturbances, including over load and short circuit disturbances. To minimize such interference, it is hoped that the protection system can meet the requirements of selectivity, reliability, sensitivity and speed, which depend on the accuracy of setting the security equipment. One of the protection equipment used is Over Current Relay (OCR) and Ground Fault Relay (GFR). In this study, an evaluation analysis of the OCR and GFR settings was carried out on the GI of Muara Tebo. The calculation result of the OCR setting on the Incoming side is TMS = 0.19, while the existing OCR data on the Incoming side is TMS = 0.24. The calculation result of the OCR setting on the feeder side is TMS = 0.14, while the existing OCR data on the feeder side is TMS = 0.11. The GFR setting on the Incoming side is TMS = 0.31, while the existing GFR data on the Incoming side is TMS = 0.45. The result of calculating the GFR setting on the feeder side is TMS = 0.12, while the existing GFR data on the feeder side is TMS = 0.11. The calculation results of relay settings with setting data are not much different or the difference is not too significant. the condition of the relay is still in good condition, the relay can coordinate well between the incoming relay and the feeder relay.
