Answer Posted / shahid bhutta
The impedance of a transformer is defined as the percentage of the drop in voltage to the at full load to the rated voltage of the transformer. This drop in voltage is due to the winding resistance and leakage reactance.
Alternatively, the percentage of a transformer can be described as the percentage of the nominal voltage in the primary that is required to circulate the rated current in the secondary.
