Abstract :
In the implementation of the 20 kV network electricity distribution activities often encounter disturbances that occur such as substations, distribution substations, and connecting substations. One of the disturbances is the corona disturbance in the 20 kV cubicle because disturbances such as corona often occur where this disturbance results in the appearance of rust at the cubicle's indoor contact position and the appearance of a buzzing/hissing sound in the cubicle. If the cubicle experiences a continuous disturbance, it can cause fatal damage, one of the most fatal consequences is exploding. One of the impacts of losses experienced by PLN is the unsold kWh meter. The method used in this research is using quantitative methods. At the PL181 substation, there is a corona disturbance in the 20 kV cubicle section. The current value at the PL181 substation when the corona occurs is the R=51A, S=50A, and T=43A phases with a blackout duration of 1 hour 5 minutes that occurs during corona disturbances. kWh is not sold during corona conditions, which is 4593.3 kWh. The cost of unsold kWh when there is a corona disturbance is Rp. 6,632,725
