摘要：

Lightning strokes on overhead transmission lines cause overvoltage surges, which propagate along the power line in the form of traveling waves. These overvoltages endangered the reliability of overhead transmission line and substation equipment. Lightning overvoltages are one of the most important factors in designing of substation and overhead lines insulation. This paper presents various lightning overvoltages in real electrical substation 220 kV due to shielding failure of overhead transmission line based on model study with ATP-EMTP software.
