Examination of electric and magnetic fields around high voltage equipment

In the whole territory of the European Union, both public and occupational exposures are controlled by the Council of the EU, itself. These are strict and clear limits based on the latest researches of World Health Organisation and International Agency for Research on Cancer. International Commission on Non-Ionizing Radiation Protection is also an important body to declare exposure limits which vary on the frequency.In Hungary, latest guidelines of EU Council became a national law. As a result of that, the inspection of occupational exposures of both electric and magnetic field became obligatory. A complete risk analysis has to be performed by accredited bodies to examine, calculate, simulate and measure the potential sources of risks; experts from medical field also must be involved to these researches.This paper introduces the practical results of a 3D simulation with finite element method regarding to both electric and magnetic exposures in the surroundings of a high voltage equipment. All the results were validated by on-site measurements, as well. With this technique, E and B field distributions can not only be analyzed, but visualized easily, as well.
