Abstract
This article described transverse electric (TE) mode properties of partial discharge‐emitted electromagnetic wave propagating in the three‐phase type gas insulated switchgear (GIS) with a series arrangement of high voltage conductors that was calculated by finite difference time domain (FDTD) method. In the calculation, comparison of TE mode properties between single and three‐phase type GISs as well as discussion on influences of defect position and sensor position were carried out. Also, approximation equation was proposed to obtain the cut‐off frequencies of TE modes in the three‐phase type GIS. © 2021 Institute of Electrical Engineers of Japan.
