The traditional fault diagnosis method of power capacitor has such shortcomings as large error and weak real time performance. For improving the real time and accuracy of fault diagnosis of power capacitor

the human-computer interaction technology is introduced into Zigbee wireless sensor network.And a kind of remote fault diagnosis method of power capacitor based on Zigbee wireless sensor network and human-computer interaction is proposed. The 10 kV #1 capacitor bank at Anqing Quanhe 220 kV substation is taken as study object. It is shown by the study result that the method proposed in this paper can improve effectively fault diagnosis rate of power capacitor and

at the same time

can achieve real time transmission of the fault data and real time diagnosis of the fault

which can provide new method and means for the power production scheduling and early warning of fault of power capacitor.
