Abstract

This paper describes one way of assessment of exposure level to electromagnetic fields of secondary electronic equipment or personnel in or close to high-voltage facilities. Assessment of fulfilling criteria regarding allowable values of magnetic flux, according regulations, was gained by numerical calculation and experimental measurement, considering geometrical configuration of high-voltage facility elements. Correct identification of electromagnetic disturbances of transmission lines has for a result optimal geometrical disposition of electronic equipment inside a high-voltage facility. Comparing a calculation results and results of experimental measuring on particular example of high-voltage facility, can lead to a conclusion that expensive measuring can be avoided, through standardization of a mathematical model and through numerical calculation of low-frequency magnetic field distribution even in conditions of the most complex geometry. Having in mind a number of locations where interaction between high-voltage facility and electronic equipment and personnel exists, a clear intention of authors, for reducing expenses of recording interaction level, is visible.
