| Abstract: | The characteristics on acoustic emission signals produced by corona discharge and polluted insulator flashover are studied and analyzed.A new method for distinguishing difference between corona discharge and flashover discharge is proposed based on difference the phase and amplitude between them,disturbence caused by corona is effectively eliminated.The key technology problem of the acoustic emission on-line detection for polluted insulator flashover is solved. |
