Two analysis models for electric field and heat transfer processes are developed to take into account the nonlinear relationship between the electric field and the electrical conductivity of Silicon Carbide (SiC) semi-conductive tape. The simulation results give a fundamental background to explain the failure of the stress grading system in inverter-driven medium voltage motors.本誌: 電気学会論文誌A（基礎・材料・共通部門誌） Vol.133 No.11 （2013）本誌掲載ページ: 591-597 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/133/11/133_591/_article/-char/ja/ Show more
