		abstract={electric power system plays an important role, one of the distribution system. The distribution system is useful for large deliver electricity to consumers. In the distribution networks there are many distractions, it can interfere with the electrical power supply to the consumers. PBO is one seat distribution system serves to anticipate the moment so electric turning off interference can be anticipated, required better coordination of the protection system so that the distribution of electricity to run well. In the distribution system is often used over current relay (OCR) and ground fault relay (GFR), and the PBO also used SUTM network and substation circuit (GH) so that the coordination of the security must work well in order to secure the network. In this paper, using quantitative methods, and will discuss feeder lesus in the substation teluk betung, where feeder consists of a safety OCR, GFR, PBO, and GH. The results obtained in the GI setting telukbetung for feeder lesus on 3-phase short-circuit current OCR tms = 0.36 incoming, outgoing OCR tms = 0.23, PBO tms = 0.12, and GH tms = 0.12. In the short-circuit current 1 phase to ground GFR tms = 0,452 incoming, outgoing GFR tms = 0.324, PBO tms = 0.214, and GH tms = 0.107.}
