要約(日本語): In this paper, a simplified model of corona discharge for the finite-difference time-domain (FDTD) computations has been
applied to analysis of lightning-induced voltages at different points along a 5-mm radius, 1-km long single overhead wire in the
presence of corona space charge around the wire. The magnitudes of FDTD-computed lightning-induced voltages in the presence
of corona discharge are larger than those computed without considering corona. The observed trend is in agreement with that
reported by Nucci et al. and by Dragan et al.. The reason for this trend is discussed.
