Homework Help: Three-phase Wye-Delta System. Plz help

  1. Apr 19, 2010 #1
    1. This is a problem in a 3-phase Wye to Delta/Wye system.

    2. The question is how to find the TOTAL average, reactive and apparent power and the power factor of the load in the figure attached? All the information needed is labeled

    3. I don't know how to find the phase voltages and the line and phase currents. So Please help me in this

    Probably homework, however:
    Convert 5 ohm resistors in delta to wye.
    Convert 5 ohm capacitors in delta to wye.
    Balanced system, so all wye points are at zero voltage.
    Analyise as one phase system.
