About vector group concept of transformers

  1. Oct 13, 2012 #1
    How we speak about the coil of primary in phase of a versus secondary coil
    this is accepted (as there is on same core)

    But question about
    we say this transformer (ex) is vector group Dy11
    that means phase difference between primary and secondary voltage is 330 angle
    !!!!!!!!!!!

    It's conflicted with that versus coil are the same phase

    !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    I have no idea what you are asking - DY11? Delta Wye? --- first part of your question seems to be about a single phase transformer, then second part a 3 phase?
