IEC 61000-2-2 is concerned with conducted electromagnetic phenomena (disturbances and signals from mains communicating systems) in the frequency range from 0 kHz to 9 150 kHz, with an extension up to 148,5 kHz specifically for mains signalling systems. It gives compatibility levels for public low voltage a.c. distribution systems having a nominal voltage up to 420 V, single-phase, or 690 V, three-phase, and a nominal frequency of 50 Hz or 60 Hz. The compatibility levels specified in this standard document apply at the point of common coupling. At the power input terminals of equipment receiving its supply from the above systems the severity levels of the conducted electromagnetic disturbances can, for the most part, be taken to be the same as the levels at the point of common coupling. In some situations this is not so, particularly in the case of a long line dedicated to the supply of a particular installation, or in the case of a disturbance an electromagnetic phenomenon generated or amplified within the installation of which the equipment forms a part. Compatibility levels are specified for conducted electromagnetic disturbances phenomena of the types which can be expected in public low voltage power supply systems, for guidance in the definition of: - the limits to be set for disturbance conducted emissions into public power supply systems (including the planning levels defined in 3.1.5). - the immunity limits to be set by product committees and others for the equipment exposed to the conducted disturbances electromagnetic phenomena present in public power supply systems.
