Answer Posted / pawar shyamkant sitaram
It depends upon the system power frequency voltage before
the fault appearing on first pole to the volage appearing
across the heathy poles after clearing the fault. The value
of first pole to clear factor is mainly decided by the
sytem grounding & ratio of zero seq.impdence to positive
sequence impedance.
