Answer Posted / mugaisi
Provide 2-phase supply on the HV side of transformer on two
phases.
Then measure magnetizing current in the supplied phases.
Then measure the voltages on the LV side.
Repeat the same for the other phases and measure current
and LV corresponding voltages.
The LV voltages should obey
ry = rb+by
and
rn = bn+yn
