1 Abstract-This article aims to prove the effectiveness of the PEEC method adapted to the modelling of meshless earth whose formulations have been explained in our first theoretical article [1]. This publication is the second part of [1]. Its robustness is emphasized on the simulation of a complex system. The chosen example is to calculate the response of a residential building struck by a lightning wave including models for all components of the distribution network. This method would allow a precise and rapid sizing of the earth protections of buildings. Today this is achieved using empirical approach or meshing methods which can be heavy and costly in terms of time solving and memory storage. An integral method based on an analytical resolution of the Poisson equation in the case of current injection has made it possible to obtain excellent results in terms of precision with a great simulation speed [1] compared to conventional methods such as finite elements. A sensitivity analysis can be undertaken through the variation of physical parameters of the earth systems in order to better design them. This method is obviously suitable for taking into account other EMC disturbances such as power electronics.

“…Using these expressions, the impact of the frequency dependence of soil parameters on the lightning performance of grounding electrodes was assessed in [10,11,13,14]. Evaluations concerning this effect for the lightning performance of transmission lines and on induced voltages were assessed in [15] and [16], respectively.…”

By means of a general approach this work presents a synthesis of recent scientific developments regarding the frequency dependence of soil resistivity and permittivity, focusing on the impact of this effect on the lightning performance of electrical systems. Specifically, it considers the impact on the response of grounding electrodes and of transmission lines subjected to lightning currents, along with the influence on voltages induced at distribution lines.
