If the phase voltage in a star connected generator is 200V what will be the line voltage?
- 115V.
- 346V.
- 200V.
Explanation from PART66Online
In a star connection the line voltage is the square root of three times the phase voltage. With a phase voltage of 200 V, the line voltage is 1.732 x 200 = 346 V. The 200 V option would apply only to a delta connection, where line and phase voltages are equal.

line voltage = phase voltage * square root of 3, so 200*1,7=346
