The difference between single-phase power and three-phase power
1. The power generated by the generator is three-phase. Each phase and neutral point of the three-phase power supply can form a single-phase loop to provide power for the user. Note that in the AC circuit, it cannot be called the positive pole or the negative pole. It should be called the line end (called the live line in civil power) and the neutral line (called the neutral line in the civil power).
