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....
| Is This Answer Correct ? | 9 Yes | 4 No |
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
| Is This Answer Correct ? | 6 Yes | 1 No |
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
| Is This Answer Correct ? | 5 Yes | 2 No |
Answer / ravindra
it's dimentinalless quantity not having any units, it can
be converted refer to primary or secondary.
| Is This Answer Correct ? | 7 Yes | 7 No |
Answer / parviz
By per unit impedance, we are able to deal with R, L and C in the same way as a resistor.

2 Answers Priyanka Electricals,
Two alternators say 1 & 2 are poised to parallel operation. But at the time of paralleing alternator 2 gets out of the system by tripping Earth fault relay. Please send me reply why this is happening?
