A study on UHF partial discharge online monitoring system verification methods

With the purpose of performing field verification on 1100kv GIS UHF partial discharge sensors, the author utilized the steep pulse signal injection method and the transfer characteristic experimental method to perform this study. The results indicate that both of the methods have feasibility for UHF partial discharge internal sensor field verification, and have very high relevance. The study obtained the attenuation characteristics of UHF internal sensors with different GIS structures, and provides advice on how to optimize the field verification of UHF sensors.
