Computation of the overhead power line electromagnetic field

This paper presents a novel computational algorithm for the determination of the overhead power line electromagnetic fields. Algorithm is based on the separation of the phase conductor currents into its longitudinal and transversal components and application of the Biot-Savart law for the computing of the magnetic field. Longitudinal component of the electric field is computed from vector magnetic potential, while two other components of the electric field are computed from the transversal currents, which are obtained by the average potential method. Typical example of the 110 kV overhead power line is also considered.
