Simulation Research of the Impact on Sensitivity by Structural Parameters of Disc-Type Inner UHF Sensors Used for GIS PD Detection

Abstract:

The UHF method is one of the most important partial discharge (PD) detection means for GIS, while sensor technique is the key factor of the UHF method. In comparison with external sensors, inner sensors can achieve higher sensitivity. The paper firstly presents a key indicator of the sensor performance evaluation, and builds a simulation model of that. Secondly, the paper implements simulation research on the PD detection performance of the disc-type sensor, especially on the impacts caused by structural parameters based on the simulation model. The research achievements of the paper may provide reference of performance evaluation and design optimization for disc-type UHF sensors.
