Answer / sanjay sharma
it is % of rated primary voltage which require to establish
sufficient flux to produce full load current in short
circuited secondary, it is used while load loss test on
transformer.

Answer / hussain
Impedance voltage of a transformer is the measured voltage apply at primary winding while the secondary winding terminals of the transformer is short circuited and is increased gradually from zero till reach to full load current flows in the Primary. This voltage is much smaller than the transformer primary nominal voltage.

Answer / ahmed
Impedanc voltage value depends on the design of the transformer. decreasing this value means good transformer materials and vice versa.

Answer / istván galamb
It is the drop (ε) of a transformer:
ε = Usc / Un x 100 = In / Isc x 100
Un = nominated primer voltage
In = nominated secunder current
USc = primer voltage to obtain the In, when the secunder
side is short cicuited
Isc = secunder short circuited current

Answer / ekanadam patlavath
simply is Impedance voltage of a transformer is the
voltage drop in transformer,
voltage drop in transfermer,from primary to secondry
voltage. this i called impedence voltage of transfoermer
