Definitions:

Phase Values

Phase values pertain to the specific measurements or quantities that characterize each phase in a multiphase electrical system, such as voltage or current levels.

Pure Reactive Load

An electrical load that consumes reactive power only, with a power factor of zero, meaning it does not dissipate real power.

Three-Phase Load

An electrical load operating with three phases of alternating current, providing more consistent, balanced power delivery.

VARs

Volt-Ampere Reactive, a unit of reactive power in an AC electrical power system.
