  • In electricity, having components of various phase: referring to an alternating-current system in which several currents of equal frequency are used, which differ from one another in phase by a definite fraction of a period, as, in the three-phase system, three currents differing by one third period, in a quarter-phase system, two currents differing by one quarter period.
