Problem 8: Three Phase Transformers with Y/A and A/Y Connections A 3-phase transformer bank consisting of three 1-phase transformers is used to step down the voltage of a 3-phase, 6600 V transmission line with a turns ratio of 12. If the primary line current is 10 A, calculate the secondary line voltage, line current and output kVA for a Y/A and A/Y connection. Neglect any losses. a) Find the secondary line voltage, secondary line current, and output kVA with a Y/A connection. V₁ ILA = Output kVA b) Find the secondary line voltage, secondary line current, and output kVA with a A/Y connection. Output kVA VLY = ILY = = [V] [A] [kVA] [V] [A] [kVA]
