Reactive power, measured in kilovolt-amperes reactive (kVAR), is the component of alternating current (AC) power that does not perform any actual work but is necessary for maintaining the voltage levels required for the active (real) power to do useful work. It is associated with the energy storage in inductive and capacitive elements of the power system.
Amperes (A) measure the current, which is the flow of electric charge in a circuit. It is a fundamental unit of electric current in the International System of Units (SI).
Reactive current (I_Q) is the portion of the total current that flows due to the reactive power in the circuit. It is associated with the energy storage elements (inductors and capacitors) in the AC system.
In inductive loads, reactive current lags the voltage, while in capacitive loads, it leads the voltage.
