Abstract

Modeling of electromagnetic wave propagation inside a GIS structure can be beneficial to understanding and improvement in sensitivity of PD detection by providing information to help determine more optimal positions for UHF PD sensors. PD pulse shape is found to have a strong influence on the distribution of UHF electric field detected at sensors installed on the GIS. This paper focuses on the effect of different PD pulse shapes to understand better EM wave propagation behavior. The time dependent EM wave propagation behavior is simulated for 3 kinds of pulse shape with different front time, time to half-value and half amplitude width and a comparison is made based on the attenuation characteristic analysis of UHF sensor locations along an L-type GIS tank. The resulting influence of different PD pulse shape sources on the UHF sensor signals is presented and discussed. The results in this paper are conducive to understanding the limitations and optimization of PD sensor positions for UHF signal detection and PD location estimation.
