Fault analysis -- Simplifying to Thevenin equivalent

  1. Nov 1, 2016 #1
    1. The problem statement, all variables and given/known data

    All voltages and impedances are in per unit values.
    After all the source transformations, why is the voltage source still 1 ?
    2. Relevant equations


    3. The attempt at a solution

    Each transformation produces something that is equivalent to what existed before the transformation. So after any number of transformations, including some that reverse previous transformations, it is inevitable that you must end up with something still equivalent to the very first arrangement.

    I actually tried solving it and I got V=-17.146 with zero angle
