Definition of "reactive power" |
That component of complex power which corresponds to storage and retrieval of energy rather than consumption. / A component of apparent power (volt amps) which does not produce any real power (watts). It is measured in VARs volt amps reactive. / 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. / The shortest distance that permits radio signals of a given frequency to travel from the transmitter to the receiver by reflection from the ionosphere. / (1) electrical energy per unit time that is alternately stored, then released. For example, reactive power is associated with a capacitor charging and discharging as it operates on an AC system. Symbolized byQ, with units of volt-amperes reactive (VAR), it is the imaginary part of the complex power. |
