Description
Summary:When we examine the lightning frequency and the lightning shielding effect of the electro‐geometric model (EGM), we need the current distribution of all lightning to the ground. The distribution of lightning current to structures is different from this distribution, but it has been used in EGM conventionally. We assumed the lightning striking distance coefficient related to the height of structures in order to obtain a result which corresponds to the observed frequency of lightning to structures, and estimated the current distribution of all lightning to the ground from data listed in the IEC 62305 series of EGM. The estimated distribution adjusted by the LLS detection efficiency agreed well with the distribution observed by LLS. © 2013 Wiley Periodicals, Inc.
