Research on degradation detection method of composite insulator based on electric field distribution method and SVM
Aiming at the problem of the lack of accurate numerical algorithm criteria of electric field distribution method in the detection of degraded insulators,a composite insulator degradation detection method combined with SVM(support vector machine)is proposed.Firstly,the axial electric field intensity measurement test of composite insulators is carried out to obtain training samples and test samples.Secondly,the parameters of penalty and the kernel function are optimized by K-CV(K-cross validation)method.At the same time,a correlation SVM classifier model for identifying degraded insulators is established.Finally,the training model is used to identify the degradation of composite insulators.The results show that the degraded insulator detection method based on electric field distribution method and SVM can effectively identify the degraded insulators in the composite insulator string,and the identification accuracy is high.
