Analytical Representation of Lightning Current Impulses

Abstract

Lightning is a natural phenomenon that generates high-magnitude current impulses, posing significant risks to electrical and structural systems. The accurate modeling of lightning current waveforms is crucial for designing effective protection systems. This paper presents an analytical representation of the lightning current impulse, focusing on its waveform characteristics, key parameters, and mathematical modeling. Various methods for approximating the current front and tail are discussed, along with simulations that illustrate the behavior of lightning strokes. The study provides insights into the analytical techniques used to model lightning surges, aiding engineers in improving lightning protection strategies.
