    Hi!

    I am busy studying distribution of Fault currents through transformers, if I have a Wye solidly grounded delta transformer and I have a phase to earth fault on the secondary side of the transformer am I correct to say that Ia, Ib and Ic on the primary side will be 0?

    If the secondary delta is grounded with a earthing transformer which is either a zig-zag or wye grounded delta transformer. Will the currents on the first transformers primary side remain 0 if a phase to earth fault occurs?

    Any assistance will be much appreciated.
