Can anyone explain what it means in problem 530, when it says "the transformer and the 12.47kV system have them X/R ration"?
I understand how the answer is calculated: basically, first you find the Zpu of 12.47 bus, added it to the transformer Zpu; then find Ssc by dividing Sbase by Zpu and finally find the Isc by dividing Ssc by (1.73xVbase).
I just don't understand how "the transformer and the 12.47kV system have them X/R ration" is a hint? What does it mean and what the is use of it?
Thanks you,
