On the Assessment of Live Line Worker Exposure to Magnetic Fields

Apart from an appreciable level of concern expressed about the possible health effects of power frequency electric and magnetic fields (EMF), exposure guidelines promulgated by internationally recognised bodies and the obligation of utilities to provide safe working environments, prompted an evaluation of magnetic field levels that utility personnel may be exposed to during live line maintenance activities. A simplified approach to assess live line worker exposure together with the findings of the exposure evaluation are presented in this paper.
