| Abstract: | Pollution flashover caused multiple trips of six 500 kV lines in Shanghai, Zhejiang and Jiangsu provinces due to an unusual heavy fog from Jan. 19 to 20 of 2004. The process of the accident was introduced and reasons of the partial pollution flashover were analyzed. Aiming at this series of pollution flashover accidents relevant anti-failure countermeasures were put forward and the destination of anti-pollution work for 500 kV lines was discussed. |
