IEC 61000-2-2 pdf download – Electromagnetic compatibility (EMC) – Part 2-2: Environment – Compatibility levels for low- frequency conducted disturbances and signalling in public low-voltage power supply systems
1 Scope and object
This standard is concerned with conducted disturbances in the frequency range from 0 kHz to9 kHz,with an extension up to 148,5 kHz specifically for mains signalling systems. It givescompatibility levels for public low voltage a.c. distribution systems having a nominal voltage upto 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 apply at the point of common coupling.At thepower input terminals of equipment receiving its supply from the above systems the severityievels of the disturbances can, for the most part, be taken to be the same as the levels at thepoint of common coupling. In some situations this is not so,particularly in the case of a longline dedicated to the supply of a particular installation，or in the case of a disturbancegenerated or amplified within the installation of which the equipment forms a part.
Compatibility levels are specified for electromagnetic disturbances of the types which can beexpected in public low voltage power supply systems, for guidance in:
the limits to be set for disturbance emission into public power supply systems (including theplanning levels defined in 3.1.5).
the immunity limits to be set by product committees and others for the equipment exposedto the conducted disturbances present in public power supply systems.
The disturbance phenomena considered are:
– voltage fluctuations and flicker;
– harmonics up to and including order 50;- inter-harmonics up to the 5o”h harmonic;
– voltage distortions at higher frequencies (above the 50t harmonic);
voltage dips and short supply interruptions;
voltage unbalance;
transient overvoltages;power frequency variation;d.c.components;
– mains signalling.
Most of these phenomena are described in lEC 61000-2-1. In cases where it is not yet possibleto establish compatibility levels, some information is provided.
