Abstract :
Automatic Breaker (PBO) or known as Auto Recloser is a protection device used by Medium Voltage Air Channel (SUTM). In the distribution network, to overcome overcurrent there are overcurrent relay (OCR) and also ground fault relay (GFR). While those relays are placed in three places, including the incoming side, on the feeder or outgoing side and the last, on the recloser side. The relay coordination between the three places is calculated with an estimated distance of 1% to 100%, which is the total number of feeders (saber feeders) that will be calculated as long as 12.5 km. The methodology used in this study is a quantitative method because it uses calculations to get the final results. For OCR reclosers, the largest short-circuit current that can be decided is 12352,4984 A while for GFR recloser is 951,9571A. The working time of the relay at the recloser at the closest distance is 0.3 s, at outgoing at 0.5 s, and incoming at 0.89 s. In the inverse standard, setting the relay's working time is based on the amount of interference current obtained.
