Changing the voltage scaling will also influence the nominal power scaling:
Scaling Nom. settings 1 to 4
parameter 9030 (power) will change ac-
cording to parameter
10 V-2500 V 1.0-900.0 kW
100 V-25000 V 10-20000 kW
1 kV-75 kV 0.10-90.00 MW
10 kV-160 kV 1.0-900.0 MW
All nominal values and the primary VT settings must be corrected after the scaling has been
changed in menu 9030.

7.30 Differential measurement

7.30.1 Differential measurement
With the differential measurement function it is possible to compare two analogue inputs and trigger on the
difference between the two values.
If the differential function is for example air filter check, the timer will be activated if the setpoint between PA
(analogue A) and PB (analogue B) is exceeded. If the differential value drops below the setpoint value before
the timer runs out, then the timer will be stopped and reset.
