CADAVID, Diego Raúl; RAMIREZ, David Alejandro; LOPERA, Freddy  e  CORREA, Andrés Felipe. MAGNETIC FIELD MITIGATION OF TRANSMISSION LINES USING PASSIVE LOOPS. Rev.EIA.Esc.Ing.Antioq [online]. 2010, n.13, pp. 9-21. ISSN 1794-1237.

A simple method to determine the magnetic field generated by transmission lines is presented in this paper. The magnetic field calculation takes into account the mitigating effects of passive loops, including their optimal position in the line by applying genetic algorithms. Calculations results are validated by case reports published in the IEEE Transactions, software package for electromagnetic field analysis, and experimental data obtained from an implementation made in the power lines at a stadium lighting tower. After the analysis, the method’s validity and feasibility of its application to transmission lines power systems are demonstrated.
