Advanced analysis of the transient impedance of the horizontal grounding electrode: from statistics to sensitivity indices

Abstract

The paper deals with a stochastic analysis of influence of randomly distributed values of certain parameters on the value of the transient impedance of the horizontal grounding electrode. Deterministic model for the transient impedance calculation is based on the antenna theory and corresponding Pocklington integro-differential equation in the frequency domain. The Pocklington equation is solved using previously developed analytical technique, thus obtaining scattered voltage at the input terminal of the grounding electrode and, subsequently, transient impedance. Stochastic collocation analysis is applied by taking into account three different random parameters and performing subsequent analysis of their respective impact.
