Voltage Drop Calculations

  1. Jul 11, 2013 #1

    This is not really homework but since it's homework style, I'll post it here and maybe benefit someone else.

    1. The problem statement, all variables and given/known data
    I need to calculate the final voltage on Bus 2 (labeled B2 in attached PDF). I am trying to do this using per units and my attempt is attached.

    The network is simply a three phase 11/433 tx (assumed to be fully loaded) with one phase going from Bus 1 to Bus 2 via a single phase tx that is loaded at 32 A.

    The final voltage I get is 213.6 V. Can someone please confirm that what I am doing is correct (particularly the single phase tx's equivalent impedance) ?.

    See attached PDF for known data.

    2. Relevant equations

    11/433 is a three phase and the 433/240 is a single phase.

    3. The attempt at a solution

    See attached pdf.
