Reactive power formula induction motor
WebAug 15, 2013 · Power factor and motor efficiency. Since reactive power does not perform any work, PF indicates the percentage of useful energy from the total energy — and is best when it’s as close to unity as possible. … WebThe formula for reactive power is Q = V × I × sin (φ), where Q is the reactive power, V is the voltage, I is the current, and φ is the phase angle between the voltage and the current. The phase angle is the angular difference between the voltage and the current waveforms and is measured in degrees or radians.
