Theoretical Analysis on Pollution Flashover Voltage Prediction Based on Leakage Current of Porcelain Insulator in Service

摘要：

　　In this Paper,leakage current obtained by laboratory was derived to calculate the pollution flashover voltage of porcelain insulators.On this basis,this Paper analyzed the basic theory of prediction of pollution flashover based on leakage current monitored in service.At the same time,the calculation results and the test results of pollution flashover voltage were compared The results showed that the difference of flashover voltage between calculation results and test results was less than 5%.It is proved that the calculation method for evaluating the flashover risk by monitoring the leakage current proposed in this Paper was effective.
