    3 phase delta delta transformer..
    I have a doubt about a 3 phase delta delta transformer..
    If one line (eg: be it R) the o/p terminal is made to touch ground or if anyone standing ground touch the line.. Then it get shocked or makes a fault current..
    I want to know what is the return path of the fault current..
    Considering all equipments including generator and all transformers are 3 phase and all windings are the same..
    Please help me to know that..

    Any chance you can give us some help here?

    The transformer, is it a Delta - Delta, a Wye Delta, a Delta - Wye or a Wye - Wye transformer?

    What is the inputs to each phase and what is the anticipated output of each phase?
