Abstract

The main effect of lightning is the induced surge voltage within power networks. The paper deals with the assessment of electric potential generated during lightning. A time domain simulation using Finite Element Method was done, considering that the lightning current flows within a discharge channel with variable lengths (15–91 m) and impedances, having various peaks (2.5–40 kA). Both 8/20 μs and 5/320 μs lightning current wave shapes have been considered. The surge voltage waveforms were determined for each lightning current. The assessment of electric potential generated during lightning through phase wire, in soil and near underground power cable was done.
