The Effect of Lightning Characteristics on the Occurrence of Back Flashover on a 150 kV Transmission Line Using ATPDraw

Lightning is one of the main sources that can cause failure in the transmission overhead line system. When lightning strikes the ground wire can cause back flashover. This research studies the effect of lightning characteristics on the occurrence of back flashover on a 150 kV transmission line. Data analysis is carried out by simulating all the parameters that have been obtained using ATPDraw software. The results of this research is used to determine how the effect of lightning characteristics on the occurrence of back flashover on the transmission line. The effect of lightning characteristics different wave fronts with same wave tails time duration resulted in overvoltage with the highest value at (1.8 x 50) µs. While for same wave fronts with different wave tails time duration, it was obtained the result of overvoltage with the greatest value at the value of (1.2 x 80) µs.
