Magnetic fields from electric power systems in living environment

Abstract

The aim of this study was to investigate the levels of extremely low frequency magnetic fields levels from previous studies to evaluate the magnetic fields from power systems in living environment Four different power system environments were studied: transmission and distribution lines, substations, distribution substations and indoor mounting in the buildings. Results were gathered together to find out the essential sources of magnetic fields in living environment. The magnetic fields from 400 kV and 110 kV transmission lines, substations and indoor distribution substations exceeded the immunity level, 3.8 μT, for electric appliances.
