CABEZAS, Krissia. D.; JIMENEZ,, Pedro.; RAMIREZ,, Juan. D.  e  CANELOS, Raúl. A.. Simulation of the electromagnetic field in an extra high voltage transmission line using the finite element method. Maskay [online]. 2021, vol.11, n.1, pp.1-13. ISSN 1390-6712.  https://doi.org/10.24133/maskay.v11i1.1724.

This paper presents the results of the simulation of the electromagnetic field on the San Rafael - El Inga 500 kV overhead transmission line using the Finite Element Method with the FEMM software. The results obtained are contrasted with the measurements made on the site. With AutoCAD, the designs of the structures were raised at 1: 1 scale, which were exported to the FEMM program to carry out the corresponding simulations of the electromagnetic field emitted by the extra high voltage transmission lines. The structures located at different altitudes above sea level were considered and different alternatives of the geometry of the transmission line were simulated to determinate the values of electric and magnetic fields in order to determinate an adequate configuration that presents low values of the electromagnetic field. Finally, through the simulations performed in the FEMM program, the resulting adequate design for an extra-high voltage transmission line is shown.
