    the question i need help with guys is "

    Three single phase step-up transformers rated at 40 MVA, 13.2 kV/80 kV are connected in DELTA-WYE on a 13.2 kV transmission line. If they feed a 90 MVA load, calculate the following:

    1. The secondary line voltage

    2. The currents in the transformers windings

    3. The incoming and outgoing transmission line currents
