The grounding system of a class of power transmission line towers involving inhomogeneous conductivemedia is modelled in order to simulate its behaviour in case that a current earth fault takes place. Thesimulation includes structural elements of the tower and provides an estimate of the grounding resistanceof the tower, assuming that a standard grounding electrode is buried as the main part of the groundinginstallation. The effect of structural elements on grounding resistance is discussed and a cuantitative estimate of this effect is evaluated.
