Calculation of lightning's EM effects on surrounding structure

Abstract

A high-intensity current that is drained to the soil by a lightning protection system generates electromagnetic interference in its immediate surroundings. A mathematical model is presented for evaluating the electromagnetic fields induced in a device (simulated by an open square turn) positioned in a vulnerable area. The model is based on the dynamic analysis of the protection system's response to a lightning stroke. It takes into account the complete simulation of the complex phenomenology tied to the partial discharges of the ground electrode.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
