Parameter Settings
In parameter 6006 the switching is made between settings 1 to 4, for the generator,
simply by choosing the desired nominal setting, just as it is for the Busbar group choice
in parameter 6054.
AC Voltage Scaling
Default AC voltage scaling is set to range 100 V-25000 V (parameter 9030). To be able
to handle applications above 25000 V and below 100 V, it is necessary to adjust the
input range so it matches the actual value of the primary voltage transformer. This
makes it possible to support a wide range of voltage and power values.
Setup of the scaling can be done in parameter 9030 from the display window shown in
the following illustration.
Changing the voltage scaling will also influence the nominal power scaling:

10 kV-160 kV 1.0-900.0 MW 10.0 kV-160.0 kV 10.0 kV-160.0 kV
NOTE: All nominal values and the Primary Transformer (PT)
settings must be corrected after the scaling has been changed in
parameter 9030.
