was proposed and verified through experiments. Before extracting features of PRPD maps, perform Gabor transform on the figures to highlight details and characteristics. Optimized SVM was applied to identify the type of insulation defect. The results of experiments showed that the diagnosis method owns high accuracy. Higher accuracy indicates that the features extracted with Gabor transform can reflect more differences of insulation defects which can help identification.
