What is the Difference Between 3 Phase and Single Phase
The difference between single phase and three phase supply: In the case of transmitting the same power, three-phase power lines can save 25% of non-ferrous metals than the single-phase power lines, and less time consumed compared with single-phase power transmission. The three-phase AC power is widely used due to the advantages above.
