Abstract

IEC 61000-2-4:2002 is concerned with conducted disturbances in the frequency range from 0 kHz to 9 kHz. It gives numerical compatibility levels for industrial and non-public power distribution systems at nominal voltages up to 35 kV and a nominal frequency of 50 Hz or 60 Hz. Compatibility levels are specified for electromagnetic disturbances of the types which can be expected at any in-plant point of coupling within industrial plants or other non-public networks, for guidance in
a) limits to be set for disturbance emission into industrial power supply systems;
b) the choice of immunity levels for the equipment within these systems.
The contents of the corrigendum of July 2014 have been included in this copy.
