Abstract :
In the distribution of electrical energy in the transmission network and can not be separated from the disturbance that can disrupt the process of electrical energy distribution either internal disturbance or interference from outside. For that required protection tools to protect it, One of the interference from outside which caused the failure of equipment in the transmission network is a lightning strike. The main protection against lightning strikes on transmission lines is the Lightning Arrester, which is where to analyze performance on a 150Kv transmission line. It is also necessary that ground electrode implements are required to improve the value of the grounding resistance whose good grounding resistance values are <1 ? in accordance with PUIL standard 2000. The type of soil used in the substation is usually a rocky type that has a resistance value of 3000 ?m Then in general the earthing resistance is measured by the fall of potential method by placing the auxiliary electrode in straight satugaris with the current auxiliary electrode and located between the measured electrode and the electrode the current. The values for the calculation data are 0.61 ? to 1 ? for Lc = 10 m and 0.34 ? to 0.5 ? for Lc = 20 m. Then for measurement data Lc = 10 m obtained from 0.42 ? to up to 0.52 ? and for Lc = 20 m obtained from the value of 0.35 ? to up to 0.45 ?. So it can be seen that the greater the distance measured, the greater resistance and the better the resistance.
