Abstract :
The paper deals with a transient voltage induced along a grounding grid using the Antenna Theory (AT) approach based on the set of Pocklington integro-differential equations for multiple buried wires of arbitrary shape. The set of Pocklington equations is numerically solved via the Galerkin-Bubnov variant of the Indirect Boundary Element Method (GB-IBEM). Once the current distribution along the grounding system is determined it is possible to calculate the transient voltage along the grounding system by integrating the current distribution over the grounding structure. The obtained numerical results are compared to the results computed by means of the Transmission Line model (TLM) featuring the Finite Difference Time Domain (FDTD) solution technique.
