Abstract

A technique is suggested to estimate an influence zone for electric field generated with high-voltage power transmission lines. This influence zone is interpreted as acting value of electric field strength generated with the power line along the major semiaxis of polarization ellipse. The zone is computed taking into account conductor and suspension strand sagging, ground effect, three-dimensional structure of a metal power transmission tower. A possibility is demonstrated to apply the technique for some real-life examples. Influence zones are calculated for these examples as applies to overhead power transmission lines.
