Description of the display window
CAUTION!
Changing the main current transformer parameters or voltage transformer
values subsequently can directly infl uence the capacitor stages for which the
stage power was determined using the auto confi guration mode. This ensures
that the stage power is adequately adjusted in case of a subsequent correction
of the transformer parameters.
Manually confi gured stages are not applied.
Setting target cos phi:
You can ask your electricity supplier for the target cos phi, which should be set
up at this point. By default, the target cos phi is set to 0.95 inductive (see the
"Default settings" chapter).
Setting the voltage transformer parameters:
Set the primary voltage in the U primary submenu, the secondary voltage
under U secondary and the phase allocation of the measuring voltage under
Rot. fi eld U. These settings apply to a standard network (voltage Ph-Ph 400 V
primary, 400 V secondary). If you use a voltage transformer, confi gure the pa-
rameters indicated on the voltage transformer, e.g. 690 V / 100 V, as well as the
measuring mode, e.g. L12 for measuring voltage connection between phases
L1 and L2.
Setting the discharge time:
Checking or, if necessary, changing the discharge time of the capacitor stages
is a very important menu item. Please make sure that the correct value is set,
otherwise the system could be damaged!
Setting the maximum stage power per switching cycle (switching operation):
To quickly compensate missing compensation power or overcompensation,
it is possible to switch identical or diff erent stage powers simultaneously. The
number of stages to be switched simultaneously is determined by the value
“Max. stage power per switching cycle”.
Example:
If there is a missing compensation power of at least 50 kvar and a limit of 50
kvar for this function, the controller simultaneously switches 2x20 kvar and
1x10 kvar, for example.
