Abstract
New engineering modified transmission line models of lightning strokes are presented in this paper. Their computational results for lightning electromagnetic field (LEMF ) at various distances from lightning discharges are in good agreement with experimental results that are usually used for validating electromagnetic, engineering and distributed-circuit models. Electromagnetic theory relations, thin-wire antenna approximation of a lightning channel without tortuosity and branching, so as the assumption of perfectly conducting ground, are used for electric and magnetic field computation. An analytically extended function (AEF ), suitable for approximating channel-base currents in these models, may also represent typical lightning stroke currents as given in \(\mathrm {IEC}~62305\text {-}1\) Standard, as well as the \(\mathrm {IEC}~61000\text {-}4\text {-}2\) Standard electrostatic discharge current.
