Stands for volt-amp reactive. In an AC power system, it is the measure of the reactive power generated or consumed. Generally referred to as imaginary power, it has a real effect in that it still must be generated and transmitted over the bulk electric grid.

var (electric power circuits) - The unit of reactive power in the International System of Units (SI). The var is the reactive power at the two points of entry of a single-phase, two-wire circuit when the product of the root-mean-square value in amperes of the sinusoidal current by the root-mean-square value in volts of the sinusoidal voltage and by the sine of the angular phase difference by which the voltage leads the current is equal to one.
