		abstract={Short circuit faults often occur in distribution channels so that a protection system is needed to minimize the impact of disturbances. The protection equipment used in the medium network is OCR (Over Current Relay) and Recloser. The writing of this final project discusses the coordination of OCR settings in the recloser protection system to calculate short circuit faults, the amount of OCR working time in the recloser as well as in outgoing and incoming feeders. The effect of OCR in this recloser is to check the overcurrent relay, whether it can still be assessed as selective or the setting value must be changed to a value that provides more selective relay work, or obtain optimum selectivity work. The results of the calculation of short-circuit faults, the longer the network, the smaller the value of the resulting fault current is due to the fact that the distance of the fault point affects the magnitude of the short-circuit fault current. Settings for OCR recloser TMS= 0.07, t= 0.28s, while OCR outgoing TMS= 36, t= 69s and OCR incoming TMS= 22, t= 88s. The working time on the recloser relay works faster than the relay on the Outgoing feeder and Incoming feeder side. The timing of the relay operation is necessary so that the disturbance does not extend to the undisturbed part. With the observation of the data obtained that the coordination of OCR in the Tuguraja recloser is still selective because the grading time provides a long time difference.}
