Electric Field Distribution and Protection of Live Working on EHV Transmission Lines with Arresters

Live working is a significant way to improve the reliability of transmission lines. In this paper, we have studied the human body electric field distribution during ground potential live working and equipotential working for the 500 kV transmission line that is equipped with lightning arresters. According to the calculation results, this paper analyzes that it is recommended to wear shielding clothing of not less than 45 dB.
