Nameplate for the tested transformer:
All these data are crucial for performing the correct measurement. MI3280 calculate
proper turn ratio according the selected vector group.
Reference Turn ratio
– Calculated Turn ratio from Voltage ratio (VH / VX) and
appropriate factor that depends on vector group)
– example for the tested power
transformer:

4. Connect the test cables to the measured transformer according the connection
diagram. Connection diagram is available under
button.
Measured cables have Kelvin clamps (crocodiles), which automatically exclude the
influence of test probes.
