Mains Voltage Harmonics
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, the
same load can cause different voltage harmonics.
For a normal mains the harmonics content of the mains voltage when
operating 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, line capacitance
related to the connection point.
