5.2.3 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.
