Evaluation of Low Frequency Electrical and Magnetic Fields in a Electrical Transmission Substation

Abstract

In recent years, there has been a stagnation in the investigation of the issues related to exposure to electromagnetic fields, as it has been deemed that their presence is not significantly apparent; however, they may induce alterations within the human body and pose certain occupational risks. It is widely accepted that these fields do not emit sufficient energy to effectuate such changes at the atomic level, yet they can have detrimental effects on the health of employees. This article delineates the findings from the assessment of non-ionizing radiation within the premises of the MULALO Electric Transmission Substation, where the reference values for exposure around the generation plant are based on public safety; conversely, within the substation, the relevant values should pertain specifically to workers exposed in occupational settings. Ultimately, these results facilitate an analysis to ascertain whether the emissions from AM No. 155, MAE, TULSMA CEM standards comply with the limits established by the International Commission on Non-Ionizing Radiation Protection, in addition to identifying the most significant values of electric and magnetic fields present within the easement strip.
