The magnetic field near power lines in the Moscow region: the results of measurements and their analyze


The aim: to analyze the real power frequency magnetic field (50 Hz) values near power lines. The material. Long-term measurements of the power frequency magnetic field (50 Hz) near power lines of 110 kV, 220 kVand 500 kVin the Moscow region. Methods. Measurements were made by tracks which were perpendicular to the wires. Length of tracks was up to 40 m. Sensor of measurer was located on 1.8 m under the ground. General quantity of measurement points were 1103. The results. Was obtained general characteristics of real values of strength of electric field and values of magnetic flux density depending to distance to the projection last wire near power lines. Conclusion. Analysis of the results has the values of the magnetic field of power lines correspond to the Russian rules in all cases. Using additional World Health Organization safety criteria for magnetic fields (the class of carcinogenic risks 2B) requires the expansion of the health safety zone 2-3 times.
