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

Answer / rvg

Impedencce voltage is nothing but self induced voltage in
reverse direction acting against the applied voltage( across
primary)
That is why after switching ON, the current intake reduces.

Dear Sir/Madam, I have one questions we have three steam turbines and one Gas turbine and our industry linked with the public network, we have protection system one of the protection is reverse power we can export just four MW only i would like to ask about how to calculate the reverse power. Thank you in advance best regards
