0 Current transformer
Note:
Only one current channel available the REG-DPA and the standard REG-DP. usually consists the
coil’s primary nominal voltage and the voltage the secondary side the voltage trans-
former.
Default value: 100 V

The jumper settings that adjust the measurement range for the power inputs from 5A
must set the same value the REG-DP.
– Nominal voltage Uns_sek
Nominal voltage the transformer's secondary side, which connected the REG-DP/
REG-DPA's measurement input.Page 129
Detailed description REG-DP/ REG-DPA parameters
0 Voltage transformer
Most P-coil's have voltage transformer measure the zero sequence voltage.
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
