Research on transmission line system simulation models with line arresters and its application

Abstract

This paper introduces the working theory of line arresters, and then discusses several models and their choose principles in simulation calculation of transmission line. At last summarizes the influence of line arrester installation number, tower grounding resistance and line span distance on the lightning withstand level of transmission line, it shows that lightning withstand level can be increased greatly with line arresters, but simulation about the effect of line arresters applying to transmission line should have further study
