(electricity) Using three separate alternating currents of the same voltage at different phases.
Three-phase transformer with four-wire output for 208Y/120 volt service: one wire for neutral, others for A, B and C phases
(electricity) Using three separate alternating currents of the same voltage at different phases.
Normalized waveforms of the instantaneous voltages in a three-phase system. The graph maps voltages over time for one whole cycle of the system. Time starts from left, and increases towards the right side. Each of the three phases starts and ends the cycle in the same value, as each cycle is (ideally) identical. The phase order is 1–2–3. This sequence repeats each cycle, and thus the rotational frequency of the generator sets the frequency of the power system. Ideally, each phase's voltage, current, and power is offset from the others' by 120°, thus having all at equidistance. This symmetry can also be recreated in converters.
