Single phase electric power
From Wikipedia, the free encyclopedia.
The generation of AC electric power is commonly three phase, in which the waveforms of three supply conduits are offset from one another by 120°. Standard frequencies are either 50 or 60 Hz. The voltage across a pair of these conduits, or between a single conduit and ground is single phase electric power. Single phase power is what is commonly available to residential and light-commercial consumers. The design of induction motorss for single-phase power incorporates special design features to attain starting torque.
