| Abstract: | The application of line arrester in lightning protection of 220 kV and above voltage transmission lines in Tianshengqiao area is analyzed. Lightning parameters in Tianshengqiao are counted by querying the lightning location system. Lightning trips of transmission line in that area since 2001 are summarized and analyzed which shows that the installation of line arresters has effectively reduced the lightning trip rate and has better lightning protection effects. Suggestions on installation position and operation ＆ maintenance of line arrester are proposed based on operation experiences and characteristic that the line arrester has protection function only to tower and phase where it is installed. |
