Abstract
As for the frequent occurrence of the faults in the 10 kV switching station
the author has found that the direct cause of such faults is moisture by way of analyzing the fault of quick-breaking trip in 10 kV switching station of 110 kV substation and analyzed the reason of the frequent fusing of PT fuses on bus I and II in the switching station
