Question
The line to neutral voltage is V for a balanced three phase star-connected load with phase sequence . The voltage of line with respect to line is given by
Correct answer
(C) 10√(3) -75^ V
Solution
Given V.
For a balanced three-phase system with sequence:
V
V
The line voltage is given by:
In a star connection, the line voltage leads the phase voltage by and its magnitude is times the phase voltage.
