【Abstract】 This paper calculates and analyzes the lightning protection features of 110kV line ZnO arrester by EMTP. The lightning withstand level of transmission line with and without line ZnO arrester is compared when the towers are stoke. The effect of grounding resistance and span on effectiveness is discussed.更多还原
