Homework Help: Cascade voltage transformer

  1. Jul 7, 2012 #1
    Got cascade voltage transformer made from two completely identical units.
    On secondary winding, load takes I2=1A
    Number of compensation and secondary windings is equal.
    I need to find current trough compensation winding Ic

    θ1 = θ2
    --> θ1 = I1N1 + IcNc - I2N2

    --> θ2 = I1N1 - IcNc

    --> I2N2 = 2IcNc

    --> Nc = N2

    --> Ic = I2 /2

    --> Ic = 0.5 A

    I did it like this and get feedback that this is wrong without explanation. So, I would be grateful if someone can explain me what is wrong here. I can post scheme if needed.
    Thanks in advance.

    Can you post a diagram labelling things? And what is theta?

    I found this is correct solution, so no need to torture you any moore.

    *Theta is electrical flow. If you are interested, I'll sent you sheme.
