	hi all in three phase line if fault occur on any one phase, the voltage on that phase will become zero .Can anyone explain me how is it becomes zero

	Voltage is current x impedance. Right? On a faulted phase, the impedance is zero; so, irrespective of the value of fault current, the voltage, which is a multiple of current & impednace - is zero only.
