| Abstract: | Several common on-line detection methods were summarized aiming at the familiar insulator faults such as stains,cracks and low resistivity,which generated in the long running process of insulators and the accidents of power grid caused by insulator flaws.The homologous detection method that suited for different flaws was confirmed and the importance of ultrasonic on-line detection was presented by analyzing and comparing the operating principles and advantages and disadvantages of on-line testing methods.The overall design idea of ultrasonic on-line detection system was presented based on the development trend of the smart grid. |
