Transformer problems

  1. Oct 9, 2016 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    I've used these formulas
    (VH/VX) = (TH/TX) = (IX/IH)
    for solving the turns although I'm not quite sure if 2400 V is the VH same as for 480 V

    for solving the ampere-turns, I = kVA/V
    where:
    V= either the VH or VX
    then multiplied the current I got to its voltage.

    Now, I'm not quite sure if my solution or my way of solving is correct.

    3. The attempt at a solution

    Can you please confirm if my solution is correct? Thanks!

    I've found that the ampere turns must be equal. Although I'm still not sure if my solution is correct. :H
