More Accurate 2D Algorithm for Magnetic Field Calculation Under Overhead Transmission Lines

Abstract

In this paper 2D algorithm for the calculation of the magnetic induction in vicinity of the three phase overhead transmission line is presented. The presented algorithm is composed of the two stages. First stage of the presented algorithm is determination of the current phasors in all system conductors including grounding wires and second stage is calculation of the magnetic induction based on results obtained in first stage of algorithm. The presented algorithm was verified by comparing with the measurement results.
