Programming the filter

Step 1: click on the Filter Operation icon.
Step 2: Select the Filter Mode tab.
Step 3: Select the option button corresponding to your chosen mode of
operation. The priorities of the selected mode are indicated at
the bottom of the window.
Click on ' Ok' if you wish to save your choice and leave the Filter
Operation mode. Click on ' Apply' if you wish to validate your
choice and stay in Filter Operation mode.
Step 4: Select the Harmonics tab.
In order to select a harmonic order, enter Y (yes) in the second
column. N (no) indicates that the corresponding harmonic has
not been selected.
The curve may be programmed in absolute terms (Amps), in %
of the fundamental current or in % of the rms current.
After choosing your appropriate reference by using the option
button, program your target in the third column for the harmonics
you have selected. The values there entered constitute the curve
and the first priority of your PQFA will be to filter harmonics until
each selected order becomes lower than its specified target.
Click on ' Ok' if you wish to save your choice and leave the Filter Operation
mode. Click on ' Apply' if you wish to validate your choice and stay in Filter
Operation mode.
