Question One: Chose the correct answer (8 Points) 300 kVA, A 13,800/480-V three-phase Y- A-connected transformer bank. It is supplied with power directly from a large constant-voltage bus. In the short-circuit test, the recorded values on the high voltage side for one of these transformers are : Vsc =560V, Isc = 12.6 A, Psc = 3300W. a) If this transformer bank delivers a rated load at 0.85 PF lagging and rated voltage, what is the line-to-line voltage on the high-voltage side of the transformer bank? b) What is the voltage regulation under these conditions?
