NCEES Power 508

508. Consider the lossles ac transformer shown in the figure. The steady-state impedance seen between terminals H1-H2 is most nearly:

I don't understand why they're using the square of the turns ratio to find the high side impedance. Can someone explain this to me? I can't find anywhere in my EERM where it shows this equation.

Thanks.

Well I just figured it out. The reflected impedance is what is "seen by the primary side. Information about it is found in section 28.4 of the EERM.
