Voltage transformer ratio
You can assign each of the 4 voltage
transformer inputs its own voltage transformer
ratio.
A voltage transformer ratio of 400 V/400 V
direct measurement is programmed in the
factory for all 4 voltage transformer inputs.
You can program voltage transformers with the
same voltage transformer ratios in addresses
002 and 003. Program voltage transformers
with different voltage transformer ratios in
addresses 012 to 043.
A change in voltage transformer values in
address 002 or 003 overwrites the contents
of addresses 012 to 043 with the voltage
transformer values from addresses 002 and
003.
