    MV grounding with 'broken/open' delta circuit

    Thanks for the posts gentlemne. I am pretty clear about what is happening now. Much appreciated

    MV grounding with 'broken/open' delta circuit

    Thanks DanDel for the response. I have probably not explained myself too well. The only ground connection is from the star point of the wye transformer. What I probably should have said is the magnetising 'impedance' is so large that the potential ground current is smaller. I have tried to add a...

    MV grounding with 'broken/open' delta circuit

    I think I have convinced my self that the megnetising current is significantly larger so the ground current should be much smaller

    MV grounding with 'broken/open' delta circuit

    I have a HRGS system using a wye primary (star point connected to ground) and delta secondary. The three phase delta is 'open/broken' at one point and a resistor included to limit the ground fault current. The question I have is, what happens to the ground impedance if the resistor is put in...
