【 摘 要 】

UHF sensor is one of the most important parts of GIS equipment partial discharge detection system, and its performance directly affects the accuracy of fault diagnosis results. UHF sensor lacks uniform standard, performs equivalent height test and sensitivity test to calibrate its performance, and builds a UHF sensor performance calibration test platform based on GTEM cell for testing. This paper mainly tests the equivalent height of different types of UHF external sensors at different installation angles. With the UHF detection system, the sensitivity test and performance comparison of each sensor are used to select the better sensor.
