A Y-connected of three identical 100-kVA 7967/277 V transformers 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 = 560 V ISC = 12.6 A PSC = 3300 W (a) If this bank delivers a rated load at 0.88 PF lagging and rated voltage, what is the line-to-line voltage on the primary of the transformer bank?(b) What is the voltage regulation under these conditions?
