Magnetic-Field Evaluation in the Vicinity of High-Voltage Electric Systems

This paper presents a simulation model of the magnetic field generated by electric energy distribution and transport facilities. The aim of this paper is to assess the models compliance with current international regulations and recommendations. One of the principal advantages of this model is its relative simplicity, since it represents the facility´s elements by using a conductor network. This network is energized by injecting a system of currents that model the load state of the facility. The conductor network is subsequently analyzed as a conventional electrical circuit. This paper applies the model to the specific case of an outdoor substation and the results are later validated when compared with the magnetic-field measurements taken at the facility.
