Approximate relationships for calculation of electric field and magnetic field intensities under power transmission lines

摘要

Power transmission lines influence natural environment by electric and magnetic fields. There is possibility of approximation of curves for variation of electric field and magnetic field with distance from the centre of the overhead lines by polynomials and by power functions. The paper presents the simple relationships for calculation of electric field and magnetic field intensities under power transmission lines for different voltages and different heights of suspensions of wires.
