Decreased SAIDI and SAIFI the Buruan Feeder Distribution Line with Insulator Cover

Abstract

The Buruan feeder is one of the electrical energy distribution systems operated by PLN South Bali. The Buruan feeders are an overhead distribution system with A3CS conductors. This feeder has several components that are open, so it is easy to get external disturbances from animals and trees. To overcome this problem, exposed components need to be isolated, one of which is with an insulator. This research found that in 2021, the value of SAIDI was 3.33 hours/year/customer, and the value of SAIFI was 7 times/year/customer. After maintenance, reconductor, and installed animal barrier, in 2022, the value of SAIDI is 0.65 hours/year/customer, and the value of SAIFI is 4 times/year/customer. This value of SAIFI is not enough for PLN UID Bali to become a world-class company. To support the PLN UID Bali to go to a world-class company, need some act to install an insulator cover. If the insulator cover was installed, the prediction of the value of SAIDI would be 0.019 hours/year/customer, and the value of SAIFI is 0.94 times/year/customer, according to the company's world-class target.
