Electromagnetic compatibility (EMC)-Environment. Compatibility levels for low-frequency conducted disturbances and signalling in public low-voltage power supply systems
电磁兼容性(EMC)
This part of IEC 61000 is concerned with conducted electromagnetic phenomena (disturbances and signals from mains communicating systems) in the frequency range from 0 kHz to 150 kHz. 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 document apply at the point of common coupling. At the power
input terminals of equipment receiving its supply from the above systems the 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 an electromagnetic phenomenon generated or
amplified within the installation of which the equipment forms a part.
Compatibility levels are specified for conducted electromagnetic 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 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 electromagnetic phenomena present in public power supply systems.
NOTE 1 More information on compatibility levels and other main basic EMC concepts is given in IEC TR 61000-1-1.Cross References:EN 61000-3-3 CorrEN 61000-4-7:1993HD 625-1 S1:1996EN 61000-4-15 (IEC 61000-4-15:1997 AS)IEC 61000-3-8IEC 60664-1EN 55016-2-1CISPR 16-1-1IEC 60050-101IEC/TR 61000-2-1EN 61000-3-3:1995IEC 61000-4-15EN 55016-1-1IEC 61000-3-3IEC 60050-161IEC 61000-4-7CISPR 16-2-1HD 625.1 S1:1996/Corrigendum:1996IEC 60868:1986IEC 60050-551:1998IEC 60038:1983 Cons Ed-6-2CLC/TR 50627:2015IEC TS 60868:1986/AMD1:1990IEC 61000-3-2:2000IEC 61037:1990/AMD1:1996IEC 60038:1983/AMD2:1997HD 472 S1:1989IEC 61000-3-7:1996IEC TR 61000-3-6:2008IEC 61037:1990/AMD2:1998IEC 61000-2-4IEC 61000-2UIE:1988IEC 61000-2-8IEC TS 62578IEC/TR 60868-0:1991IEC TR 61000-1-1IEC 61000-4-19CISPR 15EN 55015EN 61000-2-4CLC/TR 50669EN 50065-1UIE:1992IEC 61037:1990IEC 60038:1983/AMD1:1994Replaces BS EN 61000-2-2:2002+A1:2017 which remains currentIncorporates the following:Amendment, June 2019; Amendment, June 2018
