Abstract :
The lightning pillars on the highway need to be grounded in accordance with the corresponding standards. A procedure for characterization of the grounding systems placed inside the road is presented in the paper. The road is treated as a ground inhomogeneity. Using the estimation method, the road is approximated by a domain having semi-circular cross-section. The analysis includes application of the quasi-stationary image theory and the Green´s function for the point source placed inside the cylinder of the semi-circular cross-section. Leakage current distributions are obtained applying the Method of Moments. Afterwards, the grounding system characteristics are determined.
