Quarter-phase

Term · Industrial and trades · MLC-T-IND-004623

A type of alternating current (AC) electrical power system that uses two single-phase circuits with their voltages displaced by 90 electrical degrees. This configuration, also known as two-phase, requires four wires for transmission, two for each phase. While historically used, it has largely been superseded by three-phase systems due to efficiency and material cost considerations.
