Abstract :
In the medium-voltage distribution line, which in urban areas has used the underground SKTM line system which in this line connects each substation through an indoor termination channel in a 20 kV cubicle, where in this indoor termination line interference can occur caused by various factors. including the indoor termination channel which is degraded due to the old age of the equipment as well as interference from humidity in natural weather such as humidity which causes corona interference. The method used in this study is a quantitative method. To check the indoor termination, check the insulation resistance value which is checked using a megger tool, where at the disturbance of an indoor termination the insulation resistance value will be small due to insulation damage at the indoor termination. This can cause the large voltage drop on the cable line to be large due to poor insulation so that the value of the leakage current is even greater. In this final project the author will discuss how the impact of indoor termination disturbances which makes the insulation resistance value decrease so that the value of the leakage current can cause changes in the value of the large voltage drop on the incoming distribution line at the PG 291 substation and compare it with the value of the voltage drop when it is already in a state of flux. repaired.
