What is Three-phase electric power?
[[File:3-phase flow.gif|thumb|Three phase current flow]] '''Three-phase electric power''' is a method to generate, transmit and distribute [[Alternating current|AC electricity]]. It is the most common method in power systems to transfer power from [[Electricity generation|generation]] to [[Electrical load|load]]. Three-phase systems are usually more economical to be used than equivalent [[Single-phase electric power|single-phase]] or [[Double-phase electric power|double-phase]] systems. {{sci-stub}} [[Category:Electricity]]
