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
