Evaluation of magnetic field generated by power facilities in accordance with IEC 62110

This paper reports results of magnetic flux density (denoted as magnetic field hereafter) measurements under power transmission lines and around power distribution equipment. Measurements were carried out in accordance with IEC 62110 established in 2009, which prescribes measurement and evaluation procedures of uniform and non-uniform magnetic field generated by ac power systems with regard to human exposure. The average and the maximum exposure levels of magnetic field generated such power facilities were evaluated and found much lower than the reference level from the ICNIRP Guidelines.
