The line voltage of a 3 phase star connected AC generator is
- equal to the phase voltage.
- greater than the phase voltage.
- less than the phase voltage.
Explanation from PART66Online
In a star (Y) connected generator the line voltage is the phase voltage multiplied by root 3 (1.732), so it is always greater than the phase voltage; for example, 115V phase gives 200V line. The two are only equal in a delta connection, never in star.

Vline=root3*phase voltage so the correct answer is gretaer than the phase!
