3.6.4 3-phase / 3-wire connection
3.6.4.1 Connection tranformer for feature
multimess F144-PQ in 3-wire connection for medium and high-voltage via transformer
Voltage connections
Make sure that the measuring cable N / E is connected to terminal 34 for each
measurement. This is usually the earthing point of the voltage transformer.
Ensure that the switching mode (3-wire) is set (settings are described in chapter 4.3).
Set the voltage transformation ratio
Enter the nominal voltage of the conductor-conductor voltage.
Current connections
Set current transformer ratio.
Connection multimess F144-PQ current IN in 3-wire network
If a current is connected to input IN in the 3-wire network, it is
not physically measured. The current IN is always calculated in
3-wire operation.
transducer settings
The transducer settings are set in the assistant in the chapter
„Parametrization“ (see User Manual).
