First of all primary and secondary of a transformer are
decided after putting it in the service. Hence the windings
of transformer are referred as HV and Lv windings.
Now if the HV winding is connected as a secondary then
the xmer will work satisfactorily
In the another case if 220V wdg is connected to the 415V
supply the answer is same as explained by other friends.

can a 150 kva 3 phase 440v/230V delta-wye step down transformer can be use as step up transfoermer with connected loads at 440v side?
