Abstract

UHF methods have been widely used in PD detection and localization in GIS systems. Modeling of electromagnetic wave propagation inside a GIS structure can be helpful for understanding and improvement in sensitivity of PD detection by providing information to help determine more optimal positions for UHF PD sensors. This paper studies the effect of L-type and T-type GIS structures on electromagnetic wave propagation by simulating the time dependent wave propagation behavior for these arrangements of the GIS busbar. The effects of L-type and T-type structures for PD electromagnetic wave propagation behavior are presented. It is noted that if the location of the electric field detected by a UHF sensor is chosen reasonably based on knowledge of the physical structures, the measurement result obtained can reduce the attenuation affects introduced by the L-type and T-type structure.
