Definition of "VAR" |
Abbreviation for Volt-Amperes Reactive. / Volt-Ampere Reactive, Visual-aural Radio Range, Variable or Variation, Variation, Volt-amps Reactive, / In electric power transmission and distribution, volt-ampere reactive is a unit in which reactive power is expressed in an AC electric power system. Reactive power exists in an AC circuit when the current and voltage are not in phase. The correct symbol is var and not Var, VAr, or VAR, but all three terms are widely used, and VAR is widely used throughout the power industry infrastructure. The term var was proposed by the Romanian electrical engineer Constantin Budeanu and introduced in 1930 by the IEC in Stockholm, which has adopted it as the unit for reactive power. / Volt-Amperes Reactive.
