For a transformer given of 100 kVA, 220/6000-V transformer, short circuit test is performed. What current rating is needed?

For a transformer given of 100 kVA, 220/6000-V transformer, short circuit test is performed. What current rating is needed? Correct Answer 445A

For a given transformer here, test is performed on low voltage side, thus we need the value of current on the low voltage side, by dividing the reactive power by the rated voltage value, i.e. 200*1000/100 = 445A.
