Sažetak
Different approaches to the analysis of horizontal ground electrode, based on the wire antenna theory have been used in this work. The spatial distribution of the induced current along the electrode is obtained by solving the homogeneous Pocklington integro-differential equation. The spatial distribution of the scattered voltage along the electrode is computed using the generalized telegrapher’s equation. The assessment of current and voltage induced along the electrode is carried out using both analytical and numerical approaches. The numerical solution of integral expressions arising from the antenna theory model is numerically handled via the Galerkin–Bubnov scheme of the Indirect Boundary Element Method (GB-IBEM). Some illustrative results for the current and voltage induced along the horizontal electrode are given in the paper.
