Abstract

Since the on-site detection performance of high-frequency partial discharge sensors and detection devices is affected by the manufacturing process, on-site inspection environment and instrument operation and maintenance of different manufacturers, the performance research of high-frequency partial discharge sensors is of great significance. In this paper, the detection method of high-frequency partial discharge sensor performance characteristics is studied. The detection principle and method of transfer impedance and detection frequency of high-frequency sensor are introduced. The test platform of sensor performance characteristics is established. In this paper, the effects of two wiring modes on system testing are studied. The results show that both wiring methods can meet the requirements of high-frequency sensor performance testing. Through the comparison results of high-frequency partial discharge sensors from different manufacturers, the transfer impedance and detection frequency of imported high-frequency sensors are better than those of domestic equipment. The performance research of high-frequency partial discharge sensor is of great significance to the network access, arrival acceptance and periodic calibration of the high-frequency partial discharge detector, and provides a strong technical guarantee for the on-site testers.
