Thevenin reduction of network for fault analysis trouble.

  1. Nov 13, 2016 #1
    1. The problem statement, all variables and given/known data
    Reduction from top network to bottom network in the screen shot. I can not find the steps that have been taken to do this.
    Fault impedance = Zfa = Zfb = Zfc = j0.5

    2. Relevant equations


    3. The attempt at a solution
    in hand written screenshot, sorry for the mess, just to show it has been attempted.

    Looks like a Δ-Y transformation to me.

    I have just realised i have not converted from cart to pol when calculating equivalent impedance.
    doh, i think this may have been the problem

    Yes, thanks will try again with this in mind.
    thank you
