A simplistic numerical methodology for calculating the magnetic fields in open air type substations around bus bars and single line conductors is suggested based on the finite element analysis of electrodynamics equations. The suggested methodology is firstly validated through direct comparison with experimental results at the 66/11 kV substation of Latsia in Cyprus. Thereafter, the validated numerical methodology is used to predict the magnetic field values at nominal currents and the resulting fields are compared with the International Commission on Non Ionizing Radiation Protection (ICNIRP) field guidelines, dictating whether regulation limits are surpassed. It is found that the measured and the predicted magnetic field values are within the safety guidelines of the ICNIRP.
