It is found that the conductor resistance increases and the inductance decreases as the separation distance increases, i.e. the eccentricity becomes greater, due to the proximity effect. The increase of the resistance and the decrease of the inductance are more pronounced as the frequency increases. Correspondingly, the attenuation increases and the characteristic impedance decreases as the eccentricity increases. Also, a transient voltage becomes smaller and a transient current becomes higher as the eccentricity becomes greater. EMTP simulation results are confirmed to agree satisfactorily with FDTD simulation results.本誌: 電気学会論文誌B（電力・エネルギー部門誌） Vol.133 No.12 （2013） 特集：System Technical Performance（系統の技術性能）本誌掲載ページ: 954-960 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/133/12/133_954/_article/-char/ja/
