Especially, DC interruption technology using vacuum circuit breaker (VCB), which is environmentally friendly and safe, has attracted attention. In this paper, we focused on clarifying DC interruption conditions of VCB using high frequency current injection method, and conducted DC interruption test by changing circuit conditions. In addition, we modeled the DC interruption condition. Then, we evaluated the DC interruption performance with this model. Specifically, we introduced the index and probability processing. Finally, we obtained the interruption boundary of each electrode material at the first current zero point. In addition, we introduced the method for judging the interruption success or failure by comparing the random number and the interruption failure probability obtained by probability processing into the EMTP simulation. Then, we investigated the DC interruption characteristics in various circuit conditions on the EMTP.本誌: 電気学会論文誌B（電力・エネルギー部門誌） Vol.139 No.12 （2019）本誌掲載ページ: 776-782 p原稿種別: 論文／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejpes/139/12/139_776/_article/-char/ja/
