| Abstract: | Pollution flashover accident has great harm to the reliability of power supply,and when the flashover occurs on electrical equipments,the success rate of reclosing is very low,which makes power-off protection fail and leads to large-area blackout.Through analyzing typical cases,this paper obtains the concrete measures for anti-flashover to reduce the drive of flashover accident. |
