Three single-phase step-up transformers rated at 50 MVA, 13.2 kV/80 kV are connected in wye- delta on a 80 kV transmission line. If they feed an 80 MVA load, calculate the following: a) The primary line voltage. b) The currents in the transformer windings (primary and secondary). c) The incoming and outgoing transmission line currents.
