Adjective
of an electrical system that uses or generates two or more alternating voltages of the same frequency but differing in phase angle
Source: WordNetIn 1722, Warner introduced the two- and three-decade scales, and in 1755 Everard included an inverted scale; a slide rule containing all of these scales is usually known as a "polyphase" rule. Source: Internet
The field coils are connected either directly to polyphase voltage sources or to a phase-shifting reactor if a single-phase application. Source: Internet
The design, an induction motor running on polyphase current, was independently invented by Galileo Ferraris and Nikola Tesla (with Tesla's design being licensed by Westinghouse in the US). Source: Internet
In a polyphase AC system, an artificial neutral grounding system may be used. Source: Internet

The power factor of a balanced polyphase circuit is the same as that of any phase. Source: Internet
