Abstract

In order to protect high-voltage cables from lightning overvoltage and operating overvoltage, lightning arresters should be installed at both ends of the high-voltage cable. According to the resistive component of leakage current, the operating status of the zinc oxide arrester can be effectively judged. A finite element simulation modeling method for zinc oxide arrester is proposed, of which the accuracy is verified through experiments. The simulation analysis of the leakage current characteristics of 220kV arresters under different damp conditions was conducted, which provides a reference for online monitoring and early warning of the arresters.
