| Abstract: | From 2004 to 2006,110kV transmission line in Jinning,Jinlong,Ningping and Longping trips 11 times because of lightning stroke when there is thunderstorm,and it fails to reclose for 9 times.The cause is studied,and countermeasures are taken.As a result,the frequency of tripping is lowered,and the reliability of power supply by the power grid is improved. |
