(Redirected from MVAr). In electric power transmission and distribution, volt-ampere reactive (var) is a unit by 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.he reactive power (measured in units of volt-amperes reactive or var) is given by: where is the phase angle between the current and voltage. Q refers to the maximum value of the instantaneous power absorbed by the reactive component of the load.
