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

During Testing of Maintenance Free Earthing, How deep should be the Spikes of Earth Test Meter should be inserted in the soil(one spike is 15 Meter & Other spike is 30 Mtrs away from the Main Earth Electrode. Because, recently, we observed that when spike is inserted 3-4 Inch in the earth- results are better, If spike is inserted 1 feet deep than results are increasing.
