Research of effects exerted by industrial frequency electromagnetic fields on city areas located near power lines
[摘要] This paper presents the results of full scale research of electromagnetic fields of power transmission lines of various voltage classes at various distances from residential buildings along the full height from ground surface. The empirical correlation graphs of electric and magnetic field intensities versus distances from electric power lines at 1, 1.8, 3 m heights have been developed for the voltage classes of 110; 220; 500 kV, including empirical correlation graphs of electric and magnetic fields intensity versus height from ground at the sanitary protection zone lines and in uptown areas. A nomographic chart has been proposed, which is necessary to improve the electromagnetic safety of construction sites near power lines.
