Abstract :
Lightning discharges follow tortuous paths, so the usual assumption of a vertical leader channel is not realistic. This paper is aimed at exploring the influence that a non-vertical channel of the stroke leader can have on the lightning flashover rate of overhead transmission lines. The study is based on a Monte Carlo procedure implemented in an electromagnetic transients program, for which advanced models of the various transmission line parts involved in calculations have been developed
