To test Transformer we give HT side 440V to see wheather
that it is producing 17.6V on LT to verify Voltage ratio is
correct or not but when we give the 440V voltage to LT side
then what will happen to HT voltage ?

For ratio-test,the second answer may be correct.
But at the same time,if we apply high voltage in LV
side (in ratio-test also)for a longer period (in seconds),
LV winding cannot withstand, result in insulation break-
down,blown-out of fuses.
generally ratio-test is conducted with the
specified (allowable) voltage magnitude.so,practically this
much of voltage is not applied for LV side.I hope,this
answer will be correct.
