Electromagnetic Fields Estimation of the Santa Rosa-Totoras 230 kV Transmission Line

Abstract:

This article develops the calculation and estimation of the Electric and Magnetic Fields (EMF) of the Santa Rosa-Totoras 230 kV line in the Cotopaxi Province. First, the state of the art of works associated with the study of the electric field, magnetic field, and EMF in electric power systems was reviewed. Then, the transmission line route was designed using PLS_CADD software and applying the calculation methodology used by Electric Power Research Institute (EPRI), the EMF levels emitted by the line under study were determined and compared with the results obtained from the EMF calculation module of PLS_CADD. Finally, a statistical analysis was performed to determine if the EMF emissions of the Santa Rosa-Totoras line are within the limits established by the International Commission on Non-Ionizing Radiation Protection (ICNIRP), as well as the most representative values of electric and magnetic fields present within the transmission line’s right of way.
