Finite element method for calculating the electromagnetic field around an electrical transmission line

Abstract

This article presents the finite element method (FEM) application to quantify the electromagnetic field radiating around an electrical transmission line. The development of differential equations describing the physical behavior of electromagnetic fields was carried out in two dimensions, assuming that the conductors of the transmission line are infinitely long and straight. Simulation results for different line configurations under normal operating conditions are presented. The results indicate that for standard configurations, the electromagnetic effect does not seem significant; however, the use of power lines within urban areas motivates the need to quantify these effects to comply with low-frequency electromagnetic field emission standards.
