To better assess the effectivity of UHF-PD sensor/system, two types of assessment procedures were established--the simple procedure and the complicated procedure. Both procedure required GTEM-Cell system and Simulation GIS/GIL. The element structure, the diagram and the signal transmission path of GTEM-Cell system and the Simulation GIS/GIL were demonstrated. The result data indicated that the discernment of the procedure was better with more tests. The procedure covered 90% of known defects or failure cases of UHF-PD sensor/system.
