With the increasing for electrical energy, the load of society use will increase. In reality there are still blackouts due to unavoidable short circuit interference. Approximately 80% - 95% is caused by temporary interruptions concerning medium voltage network lines (JTM). Airway disruption in the distribution network is permanent and temporary, but most of it is temporary so the use of reclosers is very helpful in reducing the time out for consumers. To find out the relay settings, a short circuit calculation was obtained on the largest Sinuhun feeder from a 3 phase disturbance of 11776.9277 Ampere, while the smallest short circuit fault on a 1 phase ground fault was 650.1076 Ampere and OCR and Recloser settings were based on the calculations obtained in the short circuit current 3 OCR incoming tms = 0.2573, t = 0.8999 s, OCR outgoing tms = 0.2989, t = 0.5999 s, Recloser tms = 0.1257, t = 0.2999 s. In 1 phase short circuit current to OCR ground incoming tms = 0.3848, t = 0.9005 s, OCR outgoing tms = 0.2537, t = 0.5997 s and recloser tms = 0.12, t = 0,2999 s.} }
