Distribution of Magnetic Field and Exposure Level Around of Overhead Power Lines

This paper analyses the distribution of magnetic field sizes in the vicinity of high voltage overhead power lines (400 kV), in the context in which there is an intense concern about the effects of the electromagnetic field in the vicinity of high voltage and very high voltage power lines on the living organisms and especially on the humans. This concern is based on the assumption that exposure to extremely low frequency electromagnetic fields and especially to the 50 Hz magnetic field generated by high voltage overhead power lines can unduly affect the functioning of living cells and cause unwanted effects on health. The exposure limit values (ELVs), which produce undesirable effects on health, are different depending on the frequency range. The degree of exposure (public) results from the analysis of the values of the magnetic field quantities, obtained with the magnetic field tester, Hioki FT 3470-50. The values obtained are compared with the limits imposed by the present standards, regarding the public exposure to electromagnetic fields.
