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.本誌: 電気学会論文誌B（電力・エネルギー部門誌） Vol.135 No.11 （2015） 特集：IWHV 2014本誌掲載ページ: 656-660 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejpes/135/11/135_656/_article/-char/ja/ Show more
