Based on the fault rate of EHV power transmission line to influence the stable operation of power grids ,and fault statistics data according to the type ,area ,tripping month and auto-reclosing in the first half of southern Hebei province ex-tra-high voltage power grid ,it is concluded that the ice situa-tion ,external damage and lightning stroke is the typical fault . Through analysis and reaserch of the three kinds of typical fault ,this paper proposes some correspondingmeasures to prevent .
