VAR is an abbreviation of voltage-ampere reactive, a term that is used extensively in definition and measurement of reactive power within electrical circuits. Reactive power is the average of electrical power that is originated from active components like capacitors and inductors. This type of power is only observed in AC (alternating current) electrical circuits, and the unit of VAR is used to determine its levels. VAR control is used to manage the relationship of varying current and voltage that collectively originates from active electrical components. Writer Bio
