Term: polyphase system
Synonym1: <i>m</i>-phase system
[Preferred]
Synonym2:
Synonym3:
Symbol:
Definition: set of m interrelated sinusoidal integral quantities of the same kind, where m is an integer greater than one, all quantities having the same period but usually different phases

NOTE 1 – In some cases the phases differ by an integral multiple, including zero, of 2π .

NOTE 2 – Polyphase systems of voltages, electric currents and linked fluxes are commonly used.

NOTE 3 – The qualifiers two-phase, three-phase, four-phase, six-phase and twelve-phase are used for m = 2, 3, 4, 6, 12, respectively.

NOTE 4 – The concept of polyphase system can, under certain conditions, be extended to non-sinusoidal periodic quantities.
