what is the resultant phase shift in a 3 phase power system
including neutral if on or more phases gets grounded or
short circuited.
kindly explain in detail for the reasons...
Answer Posted / kmar_hanuman
I feel in case of any phase to ground fault the neutral
shifts its phase angle according to the grounded phase bcoz,
at thepoint of generation the phase angle is maintained and
the neutral is the resultant of the phase currents and the
the current of the grounded phase will be high..
