6.8. Voltage Transformers (VT) ratio settings
Function
The voltage inputs of the instrument may connect directly to
the power network (Vin < 250 Veff [nominal]), or through
voltage transformers (Vin > 250 Veff [nominal]).
When you connect the inputs directly you should set VT=1.
When you connect the inputs through voltage transformers
you should set the VT ratio of the applied transformers, so
the instrument able to calculate with the primary voltage.
(e.g. 1000/100 V/V, VT=10)
[VT Factory default: 1.]
1. Click on the ”Configuration” tab
2. Inside of ”Configuration” tab click on the “Measure
settings” tab.
3. Type the VT ratio value to “U transform” field.
4. Click on the “Save” button.
