Three-Phase Power
Three-phase power is an electrical supply method using three alternating currents offset in phase, commonly used for commercial and industrial equipment requiring higher power capacity.
Definition
Three-phase power delivers electricity via three alternating currents offset by 120 degrees, providing a more efficient and stable power supply for higher-capacity equipment than standard single-phase supply. It's the standard supply type for most commercial and industrial sites.
Why It Matters
Three-phase supply is mostly a technical infrastructure consideration; it's relevant to energy management primarily when metering or submetering needs to account for load balance across phases.
