Lightning-induced voltages are one of the main causes of shutdown in distribution lines. In this work, attention is focused on the effects of wideband modeling of electric grounding in the overvoltage calculation along insulator strings due to indirect lightning strikes. This study is done directly in the time-domain with the grounding being...

Indirect lightning strokes represent and important source of damage for overhead distribution lines. For the correct evaluation of lightning-induced overvoltages, the frequency dependence of the electrical parameters of the soil should be considered. Therefore, this paper proposes a simplified approach which selects a dominant frequency...
