Checking The Correct Connection Of The Cts With A Fluke 41B; Step 6: Before Starting The Filter; Step 7: Start The Filter - ABB PQFM Instruction Manual

This operation has to be repeated for the remaining two phases for a complete check.
The current probes have to be changed accordingly.

8.6.2.4 Checking the correct connection of the CTs with a Fluke 41B

The Fluke 41B is a power analyzer that allows measurements of one voltage and one
current wave. Unfortunately, the device does not allow simultaneous display of both
waveforms on the screen. However, it is possible to synchronize the triggering on either
the voltage or on the current. All phase shift measurements are then referenced to the
chosen origin. To read directly the phase shift between the fundamental components,
just select the spectrum window of the signal which is not chosen as the origin.
The instrument must be configured for single-phase measurements.
The probes must be connected as shown in

Step 6: Before starting the filter

Before switching the filter ON, ensure that all harmonics and reactive power
compensation/balancing options have been deselected.
- For deselecting all harmonics of the main filter settings at once go to
[/Welcome/Settings/Customer set./Main settings/Deselect all].
- For deselecting all harmonics of the auxiliary filter settings at once go to
[/Welcome/Settings/Customer set./Auxiliary settings/Deselect all].
- For deselecting the reactive power compensation option of the main filter
settings disable the option 'PFC type' in [/Welcome/Settings/Customer
set./Main settings/Main PFC/Bal.].
- For deselecting the load balancing option of the main filter settings disable the
option 'Balance load' in [/Welcome/Settings/Customer set./Main settings/Main
PFC/Bal.].
- For deselecting the reactive power compensation option of the auxiliary filter
settings disable the option 'PFC type' in [/Welcome/Settings/Customer
set./Auxiliary settings/Aux. PFC/Bal.].
- For deselecting the load balancing option of the auxiliary filter settings disable
the option 'Balance load' in [/Welcome/Settings/Customer set./Auxiliary
settings/Aux. PFC/Bal.].
For more information on the main and auxiliary settings concept, refer to
In multi-unit filters consisting of only masters, the master unit with the lowest address
has to be used to control the complete filter system.

Step 7: Start the filter

The PQFM contains a main contactor that is controlled by the filter controller.
