| Abstract |
The ways to improve the safety of power facilities is to install surge protection devices and grounding method to protect against the lightning surge. This paper analyzes how much lightning overvoltages are reduced by giving different rated voltage to the surge protection device and applying different grounding method when the direct lightning strike and the lightning-induced is applied separately. This analysis also contains how the distance between wind turbine and the lightning strike point affects the lightning overvoltage created by the lightning-induced. |
