Abstract

The paper deals with BEM analysis of plane wave coupling to three-phase power line. The formulation is based on the set of Pocklington equations for arbitrarily shaped wires. The presence of a lossy ground is taken into account via rigorous Sommerfeld integral formulation. The set of Pocklington equations is solved by the Galerkin–Bubnov Indirect Boundary Element Method (GB-IBEM) using isoparametric elements. Some computational examples for the currents induced along phase conductors and shield wire of the 3-phase power line are presented. The numerical results obtained via GB-IBEM are compared to the results calculated via NEC (Numerical Electromagnetic Code). The results obtained via different approaches agree satisfactorily.
