The compact configuration is characterized by the presence of an unenergized wire that has the main function to sustain the spacers of the phase conductors. As the wire could be periodically grounded, the paper analyses its effectiveness in reducing the overvoltages due to indirect lightning. The results are compared with those relevant to a conventional configuration of MV overhead lines now adopted by the same distribution company. The effects of the presence of surge arresters along the line are also analysed.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: 987-993 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_987/_article/-char/ja/ Show more
