Abstract

Interference on transmission system line Sungguminasa – Tallasa led to black out (widespread outages) SULSELRABAR on Tuesday, January 19, 2016 at 14.13. The disorder occurs along with rain and high winds accompanied thunderstorms that so hard third loss burden of 746 MW. This research aims to optimize the value of grounding resistance in the event of lightning strikes and analyze the loss due to the loss of the load. The method used is to use the ATPDraw simulation and case study in areas that have experienced disruption lightning strikes in particular line Sungguminasa – Tallasa by using the paralelisasi method of copper rod. The results of this research show that the magnitude of the grounding resistance have an average voltage exceeds the limits of the capacity of the start 1001.54 kV 1042.31 kV up to, so that the occurrence of voltage impulse flashover and back with the current disruption reaches 22.65 kA. Calculation of wave running in the wake of the failure of transmission line grounding values obtained 5.4
