Abstract :
During the implementation of electricity distribution, especially the 20 kV network, there are often disturbances at the substation, distribution substation, and connection substation. The occurrence of disturbance is usually found in the 20 kV cubicle and the impact resulting from the disturbance of the cubicle greatly affects the quality of the electricity distribution. Cubicle disorders that occur are usually caused by corona. Corona is a phenomenon that occurs when the air around an conductor or conductor is ionized and a charge is released which results in failure of insulation. Understanding Cubicle 20 kV is a set of electrical equipment mounted on a distribution substation that functions as a divider, breaker, connecting controller and protection of 20 kV voltage distribution system. This research uses quantitative methods. Can be seen in KG 68 substations affected by corona interference. The current value of KG 68 substations with Ceiling feeders measured at Pegangsaan substation is 55 A. The long duration of time to go out when the corona cubicle occurs is 1 hour 1 minute and the length of time to go out when maintenance of the substation is 1 hour 32 minutes. The kWh value that was not sold when there was a blackout due to disturbance of the cubicle corona was 1644.5 kWh and the value of kWh that was not sold during the outage due to maintenance of the substation was 2480.24 kWh. The cost of kWh that was not sold when there was a blackout due to the disturbance of the cubicle corona was IDR 2,343,412 and costs of kWh that were not sold when there was a blackout due to maintenance of substations, namely Rp. 3,534,342
