Three Phase Transformers with Y/Δ and Δ/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/Δ and Δ/Y connection. Neglect any losses a) Find the secondary line voltage, secondary line current, and output kVA with a YA connection Output kVA - [kVA] b) Find the secondary line voltage, secondary line current, and output kVA with a c onnection. AY LF Output kVA - [kVA]
