Electric and magnetic field measurements in an indoor electric power substation

This paper examines the electric and magnetic fields in an indoor electric power substation 132/11.5 kV in Cyprus. First, the results of previous relevant research studies, as well as the reference levels for safe general public and occupational exposure, given in the guidelines of the International Commission on Non-Ionizing Radiation Protection (ICNIRP), are presented. Next, basic data for the examined substation as well as a brief description of the field measurement instruments used are given. Indicative results of the electric and magnetic field measurements in the rooms of the above-mentioned indoor power substation, accompanied by relevant tables and diagrams follow. Final conclusions concerning safe public and occupational exposure to these fields are set out.
