| Abstract: | The current situation of lightning protection measures and the reasons of the accident caused by lighting in present 6 kV ～35 kV power grid are analyzed from 5 aspects,and the problems of lighting protection are also analyzed.According to the existing problems the improvement measures are proposed such as improving the surge arrester protection as well as the grounding of medium voltage power grid tower and lightning protection device,adding lightning rod or ground wire on the tower vulnerable to lightning,using clamp insulator,improving the operation rate of automatic reclosing,strengthening the operation and maintenance of the medium voltage grid |
