DISCHARGE TIME
For every single capacitor step an own discharging time can be defined. The discharging time is a blocking
time, becoming active after switching off a step. As long as this time is running (display of "
!
" in the step indi-
cation) this step is not available for the regulation. Discharging time should be adapted to the capacitor dis-
charging unit.
For step exits, which are switching thyristor switches, discharging time can be reduced to the zero.
2.4.10 Cos phi control
Switch on or off voltage control
COS PHI : U control reactive power depending on the voltage
COS PHI : P control reactive power depending on the load
NO : standard power factor control
The following items appears only when the cos phi control is set to COS Phi : U, otherwise the points
are not visible.
2.4.11 COS PHI CAP
Defines the capacitive limit for the voltage control.
2.4.12 COS PHI : U SET POINT 1
Defines target point 1 for the COS PHI : U / COS PHI : P control
SET POINT 1 uses the “COS PHI CAP” when the measured voltage is at the level which is adjusted. In fac-
tory setting this point is used when 0.98 * NOM. V
2.4.13 COS PHI CENTER
Defines the center point of the charachteristic given by the adjusted SET POINT’s 1-4
2.4.14 COS PHI : U SET POINT 2
Defines an further point on the charachteristic build between SET POINT 1 and SET POINT 4. This is also
adjusted by a voltage Level
2.4.15 COS PHI : U SET POINT 3
Defines an further point on the charachteristic build between SET POINT 1 and SET POINT 4. This is also
adjusted by a voltage Level
2.4.16 COS PHI IND
Defines the inductive limit for the voltage control.
