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.
Where "n" is the number of the phases.
In case of 2 - phase the angle is 90 degrees.

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

One cycle constitutes about 360 degrees angle. So to complete a cycle in a 3 phase individual phases are 120 degree apart from each other.

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 a balanced system the three phase voltages or currents separated by a phase difference of 120 degree.

The phase diff is same in 3 phase system so the phase diff is 360/3 Degree phase is equal to 120 Degree.

One rotation of the waveform is 360 deg. So to balance each phase are displaced at 120 deg.

In phasor representation of three phase supply the angle b/w each phase will be 120 deg.

In 3phase system total phase angle 360'.
So difference between two phase 360/3 = 120'.
So difference between two phase 360/3 = 120'.
