Measurement of power frequency magnetic fields in buildings from EMC point of view

The aim of this study is to measure magnetic fields of indoor power systems in buildings from an EMC point of view. Consideration of electromagnetic compatibility has become more important in electrical systems. Instead of conductors to appliances, measurements focused on distribution subcenters and feed cables, because of higher currents. In this study, four buildings were measured with different measuring techniques. Rooms that were considered interesting based on survey measurements, were also measured with five-point and mapping measurements. As a result of the study, it was noticed that the magnetic field immunity levels may be exceeded in buildings.
