Transient statistics from the lightning strike current flowing along grounding electrode

This paper aims to couple analytical solution of the Pocklington integro-differential equation with stochastic techniques for the statistics of transient current flowing along horizontal grounding electrode. The electrode is excited with a current source representing a lightning strike current. This problem, as it is the case for electromagnetic compatibility (EMC) issues, is governed by many uncertain parameters (lightning source profile and location, ground properties, electrode position and length, etc.). The proposed results yield additional statistical information which enable more accurate and efficient design of a grounding systems.
