Abstract

In this work approximate formulae are presented for computing the magnetic field intensity generated by power lines. Original expressions are given for double circuit lines in both super-bundle and low-reactance conductor phasing. These expressions can be used for assessing directly the right-of-way width of transmission lines related to maximum magnetic field exposure levels which may be efficiently used in environmental impact analysis. The accuracy of the approach is demonstrated by comparison with (exact) numerical computations based on the Biot-Savart’s law.
