Reactive power is also called "phantom power" because it is not apparent where it goes. The combination of reactive and true power measure in volt-amperes (VA) The dissipated power resulting from inductive and capacitive loads measured in volt-amperes reactive (VAR) Apparent power The actual amount of power in watts being dissipated by the circuit Reactive power Reactive power is one of the three types of power present in loaded circuits. An example is powering an incandescent light bulb in a reactive load energy flows toward the load half the time, whereas in the other half power flows from it, which gives the illusion that the load is not dissipating or consuming power. Another way to explain this is that reactive power is the resultant power in watts of an AC circuit when the current waveform is out of phase with the waveform of the voltage, usually by 90 degrees if the load is purely reactive, and is the result of either capacitive or inductive loads.Īctual work is done only when current is in phase with voltage, such as in resistive loads. ![]()
