What are static and low-frequency fields?

Electric field Electric fieldElectric field caused by electric charges

In industry, traffic, research and medicine as well as in every household we find electrical machines and appliances. Most of them use electric energy with a voltage of 230 or 400 Volt (V) and a frequency of 50 Hertz (Hz).

The power frequency falls within the low-frequency range of the electromagnetic spectrum.

The wires where the electric current circulates are always surrounded by low-frequency electric and magnetic fields. For electrical power transmission direct current can be used as well today. The power lines of high-voltage direct current transmission (HVDC transmission, HGÜ in German) are surrounded by static electric and magnetic fields.
