The phase sequence (or phase rotation) of the three phases of the generator must be the same as the phase sequence of the three phases of the electrical system (Grid). The generator or transformer power leads could actually be interchanged during maintenance orthe potential. .
The magnitude of the sinusoidal voltage produced by the generator must be equal to the magnitude of the sinusoidal voltage of the grid. If all other conditions are met but the two voltages are not the same, that is there is a voltage differential, closing of the AC generator. .
As previously mentioned, the phase angle between the voltage produced by the generator and the voltage produced by the grid must be zero. The phase angle (0 to 360°) can be readily observed by comparing the simultaneous occurrence of the. .
The frequency of the sinusoidal voltage produced by the generator must be equalto the frequency of the sinusoidal voltage produced. .
