A 208V wye-connected, ungrounded system suffers a ground at phase A. What is most nearly the line voltage at phase B?
The correct answer is:
SQRT(3)*208V = 360V
Can someone shed some light into this problem please? I could probably memorise this, but I want to uderstand why this is the case. Also could you argue that the line voltage between phases A and B is the same as phase B to ground? Which would make the voltage:
208V/SQRT(3) = 120V
Should the question had specified that the line voltage wanted was between phases B and C?
Thanks
