As the population increases, the electrical energy required must be directly proportional to the increasing and more reliable number of customers. SPLN 59 of 1985 which discusses 20kV reliability, a distribution system is said to be reliable with SAIDI indicators ?12,842 hours / customer / year while SAIFI ?2,415. Based on the reliability index calculation that calculates SAIDI and SAIFI at the Unreliable Payo Selincah substation, the SAIDI Coconut Feeder ? 177.02 hours / customer / year and SAIFI = 7.66 hours / customer / year, SAIDI Sawo Feeder ? 19.27 hours / customer / year and SAIFI = 2.21 hours / customer / year and SAIDI Duku Feeder?30.27 hours / customer / year and SAIFI = 12.68 hours / customer / year, and SAIDI Mangosteen Feeder ? 452.52 hours / customer / year and SAIFI = 13.37 hours / customer /year. For this reason, periodic maintenance is carried out such as rabas-discharge, network maneuvers and complete pole climbing in order to improve the reliability of each feeder. After maintenance, there was a change in the SAIDI SAIFI value for the 4 feeders, namely SAIDI Coconut Feeder ? 22.33 hours / customer / year and SAIFI = 0.79 hours / customer / year, SAIDI Sawo Feeder ? 1.10 hours / customer / year and SAIFI = 0, 19 hours / customer / year and SAIDI Duku Feeder ? 20.36 hours / customer / year and SAIFI = 0.86 hours / customer / year, and SAIDI Mangosteen Feeder ? 63.75 hours / customer / year and SAIFI = 1.34 hours / customer / year} }
