In order to analyze the data from partial discharge test of cable, the polar spectrum is drawn from multiplying the pulse amplitude by cosine and sine of phase angle. Advantage of this spectrum is present. According to the test results of 3 kinds of cable joint model, spectrum characteristics of different discharge type are studied. 16 characteristic values of polar spectrum about distribution and symmetry are calculated for the feature vector. Method of artificial neural network is used to study the pattern recognition of partial discharge. ©, 2015, Xi'an High Voltage Apparatus Research Institute. All right reserved. Source
