三相系统的三相电压依次出现的顺序被称为相序或电压的相位旋转。这由发电机

The order in which the three-phase voltages of a three-phase system appear in sequence is called the phase sequence or the phase rotation of the voltage. This is determined by the direction of rotation of the generator, but the phase sequence can be changed by exchanging any two of the three line wires outside the generator (not a line wire and a neutral wire).

The sequence of three-phase voltages in three-phase system is called phase sequence or phase rotation of voltage. This is determined by the direction of rotation of the generator, but the phase sequence can be changed by exchanging any two of the three line conductors outside the generator (not one line conductor and neutral).<br>
