| Abstract: | Several partial discharge detection methods are introduced.These methods can complement each other.The discovery,remeasuring and diagnosis of the partial discharge faults in a 35 kV switch cabinet are discussed.Moreover,the importance of partial discharge detection to condition maintenance of the switch cabinet is stressed,and the usual partial discharge spot in switch cabinet is pointed out.The sources inducing intermittent partial discharge should be paid much more attention to. |
