| Abstract: | The research of online detecting high voltage DC insulator based on electric field mapping is introduced. According to theoretic analysis, the electric field distribution curve of composite insulator has changed when conductive defect exist. In this paper, rotating method that is used to measure DC electric field is discussed and device is designed. The feasibility of rotating method and electric field method is studied in laboratory and real transmission line. The results show that the curve of good insulator has a waveform of "U", but the curve of faulty insulator has aberrance. So, electric field distribution can be used to find defect of composite insulator. Rotating method can be used to measure DC electric field of insulator, and the device based on it is effective and portable. |
