Abstract :
ABSTRACT Corona is a phenomenon that occurs in the presence of ionized conductors in the presence of air. Because this disorder cannot be directly identified through the human senses, this disturbance can be detected with a device called Ultra Transient Earth Voltage to detect Partial Discharge and humidity and a device to dequencing temperatures using thermovisions. With inspection activities to find out the measuring results of the cubicle, the inspection of two concrete substations with Berlin refiners in the PT area. PLN Bulungan substation KL 232 and KB 11. The measurement results on the kl 232 substation cubicle are partial discharge 23 dB, temperature 27 °C and humidity 86%, while the KB11B substation is partial discharge 13 dB, temperature 29 ° C and humidity 66%, then it can get the results of the calculation of power losses at each substation, KL232 substation with power losses of 7.90 kW and KB11B substations with power losses of 8.24 kW. To minimize power losses in the cubicle affected by corona, it can be eliminated by optimizing the humidity and temperature values in the cubicle. As well as removing the corona by cleaning the equipment using acetone liquid.
