Overcurrent This parameter is the ratio I
rms
/ I
50Hz,60Hz
i.e. the theoretically
determined ratio of the momentary RMS current to the fun-
damental current in the capacitor. The choke factor p of the
power factor correction system is also taken into account in
this calculation.
Total Q power This parameter is the sum of all the connected 3-phase
capacitor stage corrective powers.
Available Q power This parameter is the 3-phase capacitor corrective power still
available for switching in.
6.2.1.3 Control outputs
Main menu > Display > PQC overview > Control outputs
The overview display shows the momentary statuses of
all the capacitor stages.
Stages 1, 4, 5, 7, 10, 11: switched-out active stages
Stages 8 and 12 switched-in active stages
A permanently switched-in fixed capacitor stage is
shown as a switched-in active stage with an F.
6.2.1.4 Control diagram
Main menu > Display > Correction > Control diagram
The control diagram shows the currently selected control
characteristic curve (active control profile) and provides
visualization of the momentary operating point.
Scale: One scale division on the y-axis
represents ⅔xsmallest capacitor stage
