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.
