Abstract

Lightning characterization for engineering applications is not easy: a flash can be either of negative or positive polarity; negative flashes can consist of several strokes; the waveform and the parameters of the first and the subsequent strokes are very different from each other. This paper is aimed at exploring the influence that a complete characterization of a lightning flash will have on the flashover rate of a transmission line using a Monte Carlo procedure that has been implemented in an electromagnetic transients program
