    If The line to ground voltage is V then line to line voltage will be squareroot 3 times V. Now if one line is grounded due to ground fault. Then voltage between this line and faulted line becomes double the voltage between line to ground. I. E from line to ground and from ground to faulted phase voltage will br added
