Abstract
Power line generated magnetic fields are determined by a number of electrical and physical factors, some of them characterized by statistical variations difficult to predict. A software environment has been developed for the computation of the magnetic field generated by O/H power lines under real operating conditions. The program is based on a detailed modeling of the conductor geometry in the three dimensional space which allows the analysis of complex geometries such as intersection of different lines and/or not aligned spans. The work described in this paper shows that it is possible to assess the environmental fields generated by complex conductor configurations at any arbitrary location with no need to carry out expensive and time consuming measurement campaigns (measurements can be restricted to selected areas for validation purposes). A description of the numerical procedures developed are given in the paper, together with real case applications of mapping transmission line generated magnetic induction in residential areas.Pubblicazioni consigliate
