Step 8: Generate filter load

Once the filter is connected to the supply and is running, some filter load can be
generated to verify if the filtering is performing well.
When a harmonic load is present, the filtering performance can be tested by selecting a
harmonic, e.g. of order 11, and verifying if it is filtered properly.
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.

· Press
repeatedly until the 'Welcome' screen is displayed
· Highlight the filter start/stop menu ('PQF' item in the list). In this menu, the
'START' indication should be present.
· Press
. The filter will ask confirmation and then it will start. The main contactor
should close within 30 seconds. One second after closing, the IGBTs will start
and the filter will work under no load condition.
· The 'START' indication in the start/stop menu changes in a 'STOP' indication
once the filter is running
· If the start/stop menu reads 'ACK. FAULT' (i.e. 'acknowledge fault'), the filter has
encountered a fault that needs to be corrected before the filter can be started.
Refer to Chapter 11
· If the filter when activating the start menu displays a message to indicate that it is
remote control mode, the filter either has to be started by remote control or the
remote control mode has to be deactivated. More information about the remote
control functionality is given in
· If one of the units in a multi-unit filter system does not switch on, the unit
considered is in error. Refer to [/Welcome/PQF Monitoring/Status of units]) to
find out about the problem.
· For setting up the filter's main harmonics selection go to
