The accuracy of the lightning striking points estimated by the TOA (time-of-arrival) technique is evidenced by comparison with the actual location and is estimated less than 209m. The parameters on the front of the E-field waveforms are influenced by the attenuation of the high frequency components associated with the propagation of the wave over finitely conducting ground (so-called the propagation effect) and the average ground conductivity at the area is estimated 5-20mS/m. In general, the location of the lightning striking points estimated by the TOA is little influenced by the propagation effect when the propagation distance is shorter than 30km.本誌: 電気学会論文誌B（電力・エネルギー部門誌） Vol.132 No.2 （2012） 特集：IWHV 2010本誌掲載ページ: 144-149 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/132/2/132_2_144/_article/-char/ja/
