Abstract :
Electric power distribution system as a power distribution system that deals direcly with consumers. Therefore, the level of reliability must be considered, which is to be able to supply electricity continunously. Maintenance has an effect on increasing reliability in electric power sistems. To determine the effect of maintenance on the level of reliability in the electric power distribution system, PT. PLN (Persero) UP3 Serpong carries out total maintenance on Olympus feeder in 2017. A comparison of the number of disturbance data for 2017 and 2018 was carried out, one year after total maintenance was performed. Based on the sum of the results of the SAIFI and SAIDI reliability index calculation for Olympus feeder in 2017 after total maintenance was SAIFI = 0,298 times outages and SAIDI 0,146 hours outages. In 2018, SAIFI value was 2,97 times outages and SAIDI was 2,261 hours outages. Whereas from the summation of the results of the calculation of the ENS value and loss of PLN revenue for 2017 after total maintenance on Olympus feeder is ENS = 13204,44 kWh and loses PLN revenue of 19.374.610,17 rupiah. In 2018, the value of ENS = 93230,37 kWh and the loss of PLN revenue becomes 136.795.057,3 rupiah. From the results of the comparison above, total maintenance activities for Olympus feeder have proven effective in increasing reliability.
