Measurement
Settings
Current transformer
In the device screen, click on a current channel L1..L3.
Channel name
Name of the current channel selected in the device screen.
Current channel L1-L3
The current transformers for channels L1 to L3 must have the same transformer ratio.
Select the checkbox Current channel L1-L3.
In the Primary and Secondary fields, enter the current transformer ratio according to the specification on the rating plate of the current transformer.
Voltage transformer
In the device screen, click on a voltage connection L1..L3.
If you use voltage transformers, you must enter the transformer ratio.
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.
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.
