Differences between Single Phase(1-Phase) AC and Three Phase (3-Phase) AC
First, the voltage is different 1. single-phase electricity: 220 volts voltage. 2. three-phase electricity: a.b.c between the 380v phase voltage. Second, the property is different 1. single-phase electricity: a phase line (commonly known as a fire line) and a zero line of electrical energy transmission form, if necessary, there will be a third line (ground
