ENreactive power 
non-active power for a linear two-terminal element or two-terminal circuit

NOTE 1 Under sinusoidal conditions, the reactive power is the product of the apparent power S and the sine of the displacement angle φ: Q = S sinφ.

NOTE 2 The SI unit for reactive power is the voltampere. The special name "var" and symbol "var" are given in IEC 60027-1.

NOTE 3 Reactive power in the distribution network is normally expressed in kVAr.
