Figure 65 illustrates the principle of filtering to curve for one particular harmonic order.
The flexibility of the PQF control is such that a specific curve level may be defined for
each selected harmonic.
The default filter mode is Mode 3.
7.9.1.1.2 Selecting the harmonics with setting of curve levels
For setting up the filter's main harmonics selection go to
[/Welcome/Settings/Customer set./Main settings/Main harmonics]
For setting up the filter's auxiliary harmonics selection go to
[/Welcome/Settings/Customer set./Auxiliary settings/Aux. harmonics]
The harmonics that can be selected are presented in a table such as presented in
42.
When the PQF is operating in 4-W mode, 15 harmonics can be selected.
When the PQF is operating in 3-W mode, 20 harmonics can be selected.
