Whats the power in a 2 phase system?

  1. May 6, 2008 #1
    I have an old machine that works across two phases of a 3 three phase supply.
    the third phase is not connected.
    All the books I consult show me how to calculate power in a single phase or three phase circuit but never in a two phase circiut.
    I know the Voltage, Current and power factor of both phases
    Is the total power the sum of the two phases or is there another calculation that is made ?

    It's the sum of the power of each phase.

    Thats great it was getting a little confusing.
