Lightning arresters have a significant impact on the lightning protection level of transmission lines.The installation of most lightning arresters does not consider the actual tower structure,terrain,and economic costs,which affects the overall economic efficiency of the line construction plan and has a certain degree of blindness.To study the installation scheme of lightning arresters based on economic considerations,an electromagnetic transient model of the same tower double circuit was established.The influence of tower structure and terrain on the lightning resistance level of the same tower double circuit transmission line was analyzed,and the economic and lightning resistance levels of different lightning arrester installation schemes were calculated.This plan has certain guiding significance for the construction of subsequent transmission lines.
