An ac 500-Hz voltage with a designated value was applied to a sample sheet sandwiched between a pair of IEC (b) electrodes at 353 K (80℃) and 30% relative humidity for a designated period. The sheet surface degraded by partial discharges was then observed by a mechanical surface profilometer to measure the shape, from which the whole eroded volume was estimated. As a result, it has been clarified that polymers can exhibit superior partial discharge resistance when their melting point, molecular weight of chain repeating unit, density, weight ratio of benzene rings, and crystallinity are high.本誌: 電気学会論文誌A（基礎・材料・共通部門誌） Vol.133 No.3 （2013） 特集：2011 International Symposium on Electrical Insulating Materials本誌掲載ページ: 75-80 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejfms/133/3/133_75/_article/-char/ja/
