Measurement mode
If you are measuring the voltage and current with the 3-phase measuring
module, you can use this parameter to set whether you have connected the
voltage transformer between two phases or between a phase and neutral.
Phase angle correction
You can use this parameter to set the phase angle correction for your trans-
former circuit.
Voltage-transformer circuit
You can use this parameter to set your voltage transformer's circuit. You can
select the following options:
Option Description
1 Ph phase voltage Measurement in 1-phase grid between
the conductor and neutral conductor.
3 Ph differential voltage Measurement in 3-phase grid between 2
conductors
3 Ph phase voltage Measurement in 3-phase grid between
the conductor and neutral conductor
Table44: Voltage-transformer circuit
Current-transformer circuit
You can use this parameter to set the circuit for your current transformer.
You can select the following options:
Option Description
1 Ph phase current Measurement of phase current in 1-phase
grid.
3 Ph total current Measurement of differential current in 3-
phase grid.
3 Ph phase current Measurement of phase current in 3-phase
grid.
