Voltage connection L1 .. L3

Measuring mode

The Voltage transformer configuration card can be shown or hidden depending on whether you are working with or without voltage transformers.

• Click on a voltage connection L1-L3 in the device image.
  The Measuring mode drop-down list is displayed.

• To show the Voltage transformer configuration card, select Voltage transformer from the drop-down list.

• To hide the Voltage transformer configuration card, select Direct connection from the drop-down list.

Connection *

If you have swapped the phases when connecting, you can correct the phase assignment here.

Main measurement L1-L3

The ratio of the voltage transformers must be identical for all three phases.

Primary

Specify the input voltage according to the rating plate of the voltage transformer.

Secondary

Specify the output voltage of the voltage transformers, i.e. the voltage applied to the measurement device at terminals L1-L3.
