Performance of JLDN, a large-scale lightning location system (LLS), in lightning detection is evaluated by comparison with the ground-truth data. Detection efficiency of JLDN highly depended on the peak current of return strokes, and strokes more than 15kA in their peak values were all detected by JLDN irrespective of the polarity of the current. Absolute values of the peak current estimated by JLDN were on the average about 20% smaller than the directly measured values.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: 1009-1010 p原稿種別: 研究開発レター／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejpes/133/12/133_1009/_article/-char/ja/
