Abstract :
In the electric power distribution system, disturbances often occur in the 20 Kv cubicle, namely corona. This disturbance can reduce the reliability of the electrical energy distribution system. Corona occurs due to the influence of temperature and humidity which causes the air around the conductor to be ionized. The existence of this disturbance will result in unsold energy (ENS). The main cause of corona is because the cubicle often found a heater that does not turn on or is not installed. Heater that doesn't turn on or not installed causes the temperature and humidity to decrease so that the mass. The relative type of air in the cubicle also decreases. The way to deal with Corona findings is based on standard maintenance on 20 kV cubicles. Where at the PJ 69 substation for the ENS value of Rp. 1.274.658,81 / 3 hours for the resulting losses. While at CPD 1 for the ENS value of Rp. 1.364.634,726 / 3 hours for the resulting loss. Then at PJ 69 for SAIDI SAIFI's value, respectively, namely 0.000007726 and 0,000002575. While at CPD 1, SAIDI SAIFI's scores were 0.0007741735 and 0,00024725, respectively. The value of SAIDI and SAIFI in maintenance for three hours, if not immediately maintained, corona disturbances will make losses even greater than the values above.
