Why Three Phase?Generation of Three-Phase PowerPhases 120 Degrees ApartA simplified three-phase generator, as illustrated in Figure 1, shows three coils mounted on the armature at 120 degrees apart. Each coil generates an AC and voltage, but the power generated in each coil reaches its peak and direction at 120 degrees apart. Commercial generators mount many coils on the stator and many magnets on the armature. The in...See more on electrical-engineering-portal mechanicrealm

If it is a 1-phase system, it includes two wires, & when it is a three-phase system, it consists of either three wires (or) four wires. Both use AC power to power systems such as single-phase and three-phase units. Because the current flow using AC power is always in the direction of alternating.
Typically, phase-in power is the current or voltage between a neutral cable as well as a neutral cable. Phase means distribution of load, if one wire is used, there will be an additional load on it, and if three wires are used, then the load will be separated between them. It can be called less power for single-phase and more power for three-phase.
Three-phase current supplies a rotating magnetic field. Even though the power on each individual AC phase pulsates when it goes through the AC cycle, the sum of the power in all three phases at any point is constant.
A single-phase load can be power-driven from three-phase sharing transformers in two techniques. One is with connections between two phases, or one is with the connection between phase and neutral. Both of these will give a different voltage than a given power supply. This type of phase supply provides an output of about 230V.
