For more information on the main and auxiliary settings concept and on the setting up
of harmonics, refer to
Once the harmonic is selected, analyze the spectrum of the line currents to see if the
selected harmonic is filtered. Refer to
measurement results. If the harmonic is not filtered properly (e.g. if it is amplified),
deselect the harmonic and refer to
When harmonic load is not present, the filter can be tested by generating static reactive
power. Initially a low value can be set which can then be gradually increased to the
nominal filter rating.

Set the 'PFC Type' item to 'Static cap.' and choose the desired value for the item 'Q
static'.
For more information on the main and auxiliary settings concept, refer to
Once the reactive power is selected, analyze the filter current. Refer to
more information on displaying measurement results. Refer to
problems. Disable the reactive power setting after the test if it is not required by the
user.

8.10 Step 9: Set up the user requirements

If everything goes well at this stage, the user requirements for harmonic filtration and
reactive power compensation/balancing can be set up. Both main and auxiliary settings
can be programmed if desired.
By default the filter is set up to take into consideration the main settings only.
−
Select the desired filter mode.
−
Select the harmonics and the curve level.
−
Select the reactive power and balancing settings.
Background information on all the items discussed above is given in
At this stage, verify the functioning of the settings made for the digital I/O if possible
(e.g. remote control, local start/stop buttons).
