usually consists the
coil’s primary nominal voltage and the voltage the secondary side the voltage trans-
former.
Example for coil:
Nominal voltage 12000 nominal winding voltage 100 V
knu 12000 V/100 120
Reverse polarity
If the parameter enabled, the polarity the measurement can reversed without hav-
ing rewire.
Default value: 100 V
– knu Uprim/Usec
knu the conversion ratio for the voltage transformer the P-coil.Page 129

Note:
Only one current channel available the REG-DPA and the standard REG-DP. The volt-
age transformer defined two parameters.g.
Female multipoint connector Power inputs, e.
The jumper settings that adjust the measurement range for the power inputs from 5A
must set the same value the REG-DP., through the P-coil

– Nominal voltage Uns_sek
Nominal voltage the transformer's secondary side, which connected the REG-DP/
REG-DPA's measurement input
