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. WebStandard synchronous motors are available rated either 100% or 80% leading power factor. At 80% power factor, 60% of the motor-rated kVA is available to be delivered to the system as reactive kVA for improving the system power factor. This leading reactive kVA increases as load decreases.
