As the transformer impedance is affected by the configuration, the change of the impedance will be a good indicator for the change of the transformer configuration. On FRA measurement, the windings without measuring is set with an open circuit or a short circuit. In this paper, the experimental result about the open circuit test of FRA which can diagnose core defects etc. is described. Specifically, the influence on the impedances measurement by residual magnetic flux (RMF) and injection voltage level are described.本誌: 電気学会論文誌B（電力・エネルギー部門誌） Vol.137 No.11 （2017） 特集：IWHV2016 & JK2016本誌掲載ページ: 730-735 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/137/11/137_730/_article/-char/ja/
