Abstract :
It takes a lot of trouble to measure and calibrate the sensitivity of ultra-high-frequency couplers which are set in various gas-insulated switchgears (GIS). This paper is related to the approach of calculating the attenuation of the electromagnetic (EM) wave due to the partial discharge propagating through insulators constituting a GIS. The use of a simulator based on the finite-difference time-domain method for analyzing the three-dimensional transient EM fields shows the degree of precision of the modeling descriptions employed and their ability to confirm experimental results.
