Answer / nagaseshareddy.m

significance of per unit impedance is reducing the
complexity of calculation. Zp.u=actual
impedance/baseimpedance

Answer / praveen

In power system values of impedence will be large so to
reduce its complexcity in calculation it is expressed in
per unit....

Answer / mafika

p.u impedance represents the amount of volt drop that's
going to occur in the transformer and also helps in the
fault calculations

Answer / tiwari

P.u calculation is done to
simplify the calculation per
unit impedence is
convenient in case of
transformer because both
primary and secondary p.u
impedence is same

Answer / ravindra

it's dimentinalless quantity not having any units, it can
be converted refer to primary or secondary.

Answer / parviz

By per unit impedance, we are able to deal with R, L and C in the same way as a resistor.
