In alternator the three phase windings are set in 120 degrees displacement each other.

The phase difference in 3 phase power system is the same. A complete circle has 360deg. Therefore, the voltages are separated by 120deg, 360/3=120.

For the phase circuits other than 1 and 2. The phase angle can be calculated by using the formula "360/n".

Where "n" is the number of the phases.

In case of 2 - phase the angle is 90 degrees.

Each phase placed on 120 degree phase angle.

In 3-phase s/m voltage are separate by 120.

Total 3 phase 360 for each phase 120.

Total take complete in one rotation then formed 360 if division by 3 then come 120 so we take phase difference in three phase 120.

In three phase system the phase sequence with angle 120°.

Nice answer with the clear explanation, Thank you all.

In 3-phase balaced s/s, the 3-phase are 120' part from each other.

Since, phase voltage are 120' appart to each other in a similarly mannar, the line voltage will be 120' appart to each other.
