Impedence is the composition of Resistance and Inducatance
of the transfromer.

And inductance should be 5% of the transformer rating.

Answer / abdul wajid

The impedence (z) of Transformer is the total resistance
offered by Transformer .Transformer is indicated by its
losses iron and core losses

Answer / sivaramakrishnan.s

You can see the %impedance in the nameplate details.
Transformer designed depend on the full load Current.
Actually.. How much %primary voltage required to flowing the full load current at secondary side when secondary is short circuited called as %imp volt in transformer. It will be %volt of Transformer primary voltage..

THE VOLTAGE DROP RESULTING FROM REFERENCE CURRENT AS
PERCENTAGE OF REFERENCE VOLTAGE IS CALLED IMPEDANCE

Answer / s.arunkumar

transformer is always interposed between a primary source
of energy and a secondary that makes use of that energy.
Hence, the transformer constitutes an impedance to current
flow from source to load. The higher that impedance, the
more voltage drop will occur for a given load current. If a
secondary fault occurs, its effect on the circuit will be
lessened to the extent that transformer impedance
increases. The circuit designer therefore needs to know the
value of transformer impedance.
