MAGNETIC FIELD COMPUTATION DUE TO HIGH VOLTAGE POWER LINES USING EasyMAG

The vicinity of residences to overhead power lines has been a factor of concern for public health. Several studies have been developed in order to establish a relationship between the magnetic fields due the power lines and the health of people. In this paper it is presented a magnetic field computation using the software tool EasyMAG developed by the authors [4], considering several overhead power lines configurations. The software runs under Matlab© environment. One of the configurations considered was the 60kV overhead power line which goes over the Electrical and Computer Engineering Department at the University of Coimbra. This line is right over the Library so there was the particular interest to observe if the international reference levels for the magnetic field are not exceeded. For all the cases considered is this paper it is observed that the values obtained are far below the maximum limit of 100μT.
