4.2.3 Operation on public supply systems (compliance with EN 61000−3−2)
The European Standard EN 61000−3−2 determines limit values for limiting
harmonic currents in the supply system. Non−linear loads (e.g. frequency
inverters) produce harmonic currents which may "pollute" the supply system
and thus have an impact on other consumers.The standard wants to ensure the
quality of the public supply system and reduce the mains load.
)
Note!
The standard only applies to public supply systems. Supply systems
which have their own transformer substation as common in
industry are not public. The standard does not apply to them.
If a device or machine consists of several components, the limit
values of the standard apply to the entire unit.
