Abstract :
Konsumen feeders equipped with over current relay protection equipment, ground fault relay. Installed automatic return cover , this equipment functions as protection in a distribution system, because the medium voltage distribution system has a large area and is close to the customer so that disturbances occur that can cause disruption of the distribution system. Airway interference in the distribution network is temporary and permanent, but most are temporary. More than 70% of temporary disturbances occur in the airways. This study uses quantitative methods. Therefore PBO protection is used and coordinated with OCR and GFR relay on incoming and outgoing feeders. Due to the existence of the protection system, there is a need for selective protection coordination, in order to improve the performance of the protection system. The results of the settings obtained at Pasar Kemis GI for Consumer feeders for incoming short-circuit 3 OCR phases tms = 0.262, OCR outgoing tms = 0.396, PBO 1 tms = 0.355 and PBO 2 tms = 0.196. At 1 phase short circuit to ground GFR incoming tms = 0.452, GFR outgoing tms = 0.324, PBO 1 tms = 0.214 and PBO 2 tms = 0.107.
