| Abstract: | The paper statistically analyzes law of lightning distribution in the corridor of transmission lines in Gaoming district of Foshan city, Guangdong province. In accordance with characteristic parameters of lines and topography, the paper ex- plores installation feasibility of external separate lightning rod and installation requirements, introduces operating lightning protection principle of coupled ground wire and overvoltage protector in operation. Installation requirements are determined by simulation and differentiation strategy of lightning protection is conduded. |
