ABOUT TRANSFORMERS

[ILIANA40]

CAN ANYONE ANSWER TO THIS QUESTION IN PARTICULAR?

CONSIDER A THREE-WINDING TRANSFORMER WITH THE FALLOWING PARTICULARS:
Zp=Zs=Zt=0.02+j0.08
V2=400
I2=60/-30 GRAD.CELS.
I3=50/-40 GRAD.CELS.
ASSUME V2 IS THE REFERENCE PHASOR, CALCULATE V0, V1, I1, V3,
THE APPARENT POWER AND THE POWER FACTORS AT THE PRIMARY, SECONDARY AND
TERTIARY TERMINALS
THE TRANSFORMER EFFICIENCY

JUST WANT TO DOBLE CHECK MY ANSWER.

I APPRECIATE ANY HELP.

THANKS!

Ah, but this is Usenet, and we will tell you that you got it right,
you got it wrong, you got the right answer for the wrong reasons, and
everything in between.
