ANÁLISE DE CAMPO ELÉTRICO E MAGNÉTICO NAS PROXIMIDADES DE UMA LINHA DE TRANSMISSÃO OPERANDO EM REGIME PERMANENTE: verificação de valores de acordo com a norma

Abstract

The scientific community is making an effort to take measures to minimize the non–ionizing radiation e nearby regions as regards safety in operating electromagnetic fields made by transmission lines, human beings and other elements which are place in the passage strip, thus this work analyses electric and magnetic field levels which are close to permanently operating transmission lines. The proposed goal was achieved through a computer simulation on an electromagnetic model, applying Maxwell equations as well some theorems and additional methods, e.g. RMG, complex images method, superposition theorem and soil modeling. Following a sequence of methodic criteria and using specific parameters of real models of transmission lines and regarding its geometric and electric characteristics, the collected data was fed onto a computer program known as Matlab®, in which the equations outcomes are shown through charts and tables set to the same measuring scale published in the literature. The obtained results are a match to the (in loco) estimated quantified values in the literature, providing the physical consistency of the applied methods.
