    line to ground fault is unsymmetrical fault it consists all three components.un ground alternator means it consists postive sequence and negative sequence components but not zero sequence component.
    generally alternator consider as wye connection therefore depends upon parameters of transformers and transmission line.


    alternator->transformer->transmission line->load
