BEM analysis of plane wave coupling to three-phase power line

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 (GBIBEM) 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.
