The output of generator having 120 degree phaseshift. Ever time the instantaneous magntiude will be root 3 times the phase voltage. The magnitude will be same. While measuring we are considering the two phases which is maximum.

The Phase voltage of an generator is 220 - 230 V but the Phase to phase voltage (Line Voltage) will be 400 V. Voltage of R - Phase-230 Y - Phase-230 B - Phase-230 but RY-400V BY-400V ...
