Three-Phase Electricity
Document Actions
Electricity in the U.S. transmission system is Alternating Current (AC), meaning the direction of the current alternates as a sinusoidal wave. In three-phase current there are three sinusoidal current waves traveling simultaneously, each in a separate conductor. The staggered phases of the electricity make for a more constant power transfer. Transmission, subtransmission and some distribution lines carry three-phase electricity.
