Representation and analysis of the equivalent lightning protection system network for nonlinear problems in the electromagnetic interference control

Abstract

A model is described for the evaluation of the transient behavior of a lightning protection system during the draining to earth of a lightning current. The dynamic analysis is executed taking into account the possible nonlinear ionization phenomena. The model is based on the evaluation of the electromotive forces induced in open square turns by spatially distributed lightning current through the protection system. The user-friendly model implementation simplifies the preliminary analysis for the minimization of the EMI (electromagnetic interference) risk during a lightning stroke.<>
