Computation of the power line electric and magnetic fields

This paper presents a novel numerical algorithm for computing of the power line electric and magnetic fields. Phase conductor currents are separated into their longitudinal and transversal components. Computation of the magnetic flux density is based on the Biot-Savart law. Longitudinal component of the electric field intensity is computed from vector magnetic potential. Two other components of the electric field intensity are computed from the transversal currents, which are obtained by the average potential method.
