ABSTRACT - Reliability of a distribution system is the ability of the system to provide a sufficient supply of electric power with satisfactory quality. Increased demand for electricity, demands a higher level of reliability in the supply and distribution of power. The purpose of this study was to calculate the reliability level of the 20 kV distribution system at UPJ Mojokerto using the Failure Mode Effect Analysis (FMEA) method, where the value of the failure index of each major equipment distribution system was calculated to find the overall system reliability index value. Case studies conducted at PT. PLN (Persero) UPJ Mojokerto to see the effect of the number and location of the placement of sectionalizers along the network against the system reliability index. The results of analysis on Ivory feeders obtained SAIFI values based on the FMEA method were 3.80237 and the simulation was 3.8174 while those for SAIDI values were 11.9697 and 12.1197. And for Bangsal feeders, the SAIFI value based on the FMEA method is 6.82974 and the simulation is 6.4743 while the SAIDI values are 13.9370443 and 14.5671. The value of SAIFI and SAIDI for Ivory feeders and Bangsal has not yet reached the standard value set by PT. PLN (Persero), it needs to be improved in order to achieve good distribution system reliability.
