Abstract :
At the Distribution Station, there is often a disturbance in the corona of the 20 kV cubicle which can affect the supply of electrical energy. Corona if left unchecked will cause interference. Corona is a partial discharge that occurs in the dielectric material of electrical equipment. A 20 kV cubicle is a set of electrical equipment mounted on an electric power distribution substation. The method used in this research is quantitative method In CB120 substations, coronary disruption occurs in the cubicle. The current value on the cubicle under corona conditions are Phase R = 200 A, Phase S = 91 A, Phase T = 270 A and in the cubicle conditions are not corona Phase R = 308 A, Phase S = 109 A, Phase T = 314 A. The duration of blackout in the corona condition is 2 hours 20 minutes and the duration of blackout in the non corona condition is 1 hour. kWh is not sold when corona condition is 40.752 kWh and kWh is not sold when the corona is 22.790 kWh. Unsold kWh cost incurred when not corona Rp 59,783,184 and unsold kWh cost when not corona Rp 33.432.930.
