The recognition of PD( Partial Discharge) caused by different types of defects in high-voltage cables is difficult,especially the recognition of PD caused by cable insulation defects with high similarity. The CNN( Convolutional Neural Network)-based PD pattern recognition method for high-voltage cables is presented. The influences of different network layers,activation functions and pooling methods of CNN on recognition effect are studied. The proposed method is also compared with SVM( Support Vector Machin...
