    Hi. I am a bit confused with the DC component in a fault, ie a phase to earth fault. Why does this DC component decay?? Where is the energy going?

    Thanks

    Perhaps if you explained what you mean by the DC component of a fault being phase to earth?

    The part of the fault curve which raises it above the zero line making it assymetrical.

    You don't have *phases* in a DC supply, do you mean AC?

    Transient DC offset in AC fault currents is a well-known phenomenon.
    This is surely the wrong forum for this question.
