Having or producing two or more phases; multiphase; as, a polyphase machine, a machine producing two or more pressure waves of electro-motive force, differing in phase; a polyphase current.

A term that describes systems or units of a system that are activated by or which generate separate out-of-phase voltages. Typical polyphase systems are 2-phase and 3-phase; their voltages are 90- and 120-degrees out of phase, respectively. This term means the same as MULTIPHASE.

of an electrical system that uses or generates two or more alternating voltages of the same frequency but differing in phase angle
