A 25 kVA, 550/220 volt transformer has rated copper loss of 350 watts. With the low voltage winding short circuited, it requires 25 V across the high voltage winding to permit rated current through both windings of the transformer. What is the percent impedance of the transformer? A. 5.26% 8.4.55% C. 8.53% D. 9.42%
