a) What should be the KILOVOLT-AMPERE rating of each transformer in a V-V bank when the three phase balanced load is 50 KVA? (b) If a third transformer is added to complete the delta-delta con nection, what is the rated capacity of the bank? Compute for the per cent increase in capacity due to the addition of the third transformer. Ans. 28.75; 86.25; 72.5%
