    If I feed a balanced signal into two of the star side outputs of a 3 phase
    star delta transformer how will this come out at the 3 delta side outputs
    WRT earth (ground). Assume 1:1, 100% efficiency and no phase shift (or 180
    if you prefer but no complex phase shifts). How would it come out of the
    remainig star winding?

    Trying to get my head round it and confused myself.

    Because I need to prove that the signal is not going through the
    transformer. If it were going through the transformer then I will be able to
    work that out from the state of the signals present on the delta side, if it
    is getting to the delta side by some other means ie insufficient grounding
    or faulty earths then the signal on the delta side will not be phased
    correctly and the amplitudes will be wrong. I know these transformers will
    not pass HF signals but I need to prove that this particular one isn't and
    it is in circuit, lotsa volts.
