    Refer Fault Currents

    How do you refer fault currents across a delta/wye transformer in a line/ground fault using symmetrical components.

    Unbalanced Faults using Symmetrical Components

    Thanks for the response, OK so solidly earthed per se does not mean ignore effects of earth fault loop impedance, however, the problem does not specify a value for Zn, we are given no impedance nor is it mentioned in the question. I am just trying to understand how I would know if I had to...

    Unbalanced Faults using Symmetrical Components

    For a line to ground fault with a delta star load transformer, solidly earthed. I am having trouble dealing with the source reactance, do I consider this for positive and negative sequence but ignore for zero? Does solidly earthed mean that I do not need to include earth fault loop impedance in...
