Electric- and Magnetic-Field Measurements in an Outdoor Electric Power Substation

This paper investigates the electric and magnetic fields values in the area of an outdoor electric power substation 2 times 50 MVA, 150/20 kV, in Xanthi, Greece. Results of previous relevant measurements and calculations, as well as the reference levels in force for safe general public and occupational exposure, are presented first. Basic data for the examined substation along with a brief description of the field measurement instruments used follow. The main results of the field measurements in the area of the aforementioned substation are presented in relevant tables and diagrams. Final conclusions, concerning safe public and occupational exposure to these fields, according to the international guidelines, are set out.
