Abstract

It is of importance to detect a partial discharge (PD) in a gas-insulated switchgear (GIS) and to estimate its current magnitude and charge amount. In this paper, electromagnetic fields generated by a PD in an 84-kV-class three-phase test GIS have been measured with a differential voltage probe installed on the outer surface of an insulation spacer of the GIS tank, and the corresponding simulations have been carried out using the finite-difference time-domain (FDTD) method. FDTD-computed time-domain voltages across spacers agree reasonably well with the corresponding measured ones.
