A component of apparent power (volt-amps) which does not produce any real power (watts) transfer (the sine of the phase angle between the current and the voltage). [Go to source

Reactive power is the difference between apparent power and real power. It is calculated by subtracting real power from apparent power. Reactive power is measured in VAR (volt-amps reactive) or kVAR (kilovolt/amps reactive)

The portion of Apparent Power that does no useful work in an Electrical Circuit. It is commonly measured in kilovars ( kVARS) and must be supplied to most types of equipment with "Coils" of Wires using magnetic fields (i.e. Motors) to magnetize the Motor Windings. It is supplied by the Generator or by Capacitors.

Reactive power is power that flows back and forth between the inductive windings of the generator and the inductive windings of motors, transformers, etc., which are part of the electrical load. This power does no useful work in the electrical load nor does it present load to the engine. It does apply load to the generator and limits the capacity of the generator.

the portion of apparent power that does not do work. It is measured in kilovars. Reactive power must be supplied to most types of magnetic equipment, such as motors. It is supplied by generators or by electrostatic equipment, such as capacitors.

Also called imaginary power or wattless power. It is the power value in "volt amps" obtained from the product of source voltage and source current in a reactive circuit.

The power consumed in a purely inductive Alternating Current (AC) circuit; the current lags the voltage by 90Â°. Expressed in units of volt-amperes-reactive, abbreviated VARS.

The power that oscillates back and forth between inductive and capacitive circuit elements without ever being used. The function of reactive power is to establish and sustain the electric and magnetic fields required to perform useful work.

The sine of the phase angle between the current and voltage waveforms in an AC system.

Reactive power is the product of the voltage, current and the sine of the phase angle, and is measured in kiloVolt-Amps reactive (kVAr).

The background energy movement in an alternating current system arising from the production of electric and magnetic fields. Reactive power is provided by generators, synchronous condensers, or electrostatic equipment such as capacitors and directly influences electric system voltage and must be supplied to most types of magnetic equipment, such as motors and transformers. Usually expressed in kilovars (kvar) or megavars (Mvar).

The rate at which energy is stored and alternately returned to the source by a capacitor or inductor. the unit is the VAR.

The electrical power that oscillates between the magnetic field of an inductor and the electrical field of a capacitor. Reactive power is never converted to non-electrical power. Calculated as the square root of the difference between the square of the kilovolt-amperes and the square of the kilowatts. Expressed as reactive volt-amperes.
