A Wye-Delta transformer is connected to a 66 kV input three-phase transmission line. Each transformer is rated at 1000 kVA and has a step-down ratio of 8:1. The bank supplies a balance load having a power factor of 0.8 lag with a load current of 70 A. Assume ideal transformer, determine. a. The primary line and phase voltages b. The secondary line and phase voltages c. The secondary line and phase currents d. The apparent and active power at the load e. Total kVA capacity of the transformer
