Harmonics on Mains Voltage
The voltage harmonics depend on the structure of the mains, especially on
the mains inductance or the mains short-circuit power at the connection point.
At different mains and mains connection points, one device can cause differ‐
ent voltage harmonics.
For a normal mains, the harmonics content of the mains voltage when ope‐
rating drives generally is below 10%. Short-time drops in mains voltage are
below 20%.
More precise values can only be calculated with exact knowledge of the
mains data (mains topology), such as line inductance and line capacitance
related to the connection point.
These values, however, can temporally vary quite strongly, according to the
switch status of the mains. The harmonics of the mains voltage thereby
change, too.
Rough estimated values of the mains data are not sufficient for pre-calcula‐
tion of the harmonics, as mainly the resonance points always present in the
mains have a strong influence on the harmonics content.
In order to keep the degree of mains voltage harmonics as low as possible,
you should, if possible, not connect capacitors or compensation units (capaci‐
tor batteries) directly to the mains. If capacitors or compensation units are ab‐
solutely required, you should only connect them to the mains via chokes.
