kW to kVAR Calculator:
Enter the real power in kilowatts (kW), enter the power factor to get the results of kVAR.
kW to kVAR Calculation
Reactive power Q(kVAR) in kilo volt-ampere reactive is equal to the power factor times of the real power P(kW) in kilowatts. Hence we can calculate the reactive power in kVAR formula,
kVAR = kW * tan (power angle)
Q(kVAR) = P(kW) * tan(φ)
If you know the power factor then,
Q(kVAR) = P(kW) * tan(cos-1(pf))
Example:
Calculate the reactive power in kVAR for the 7.5 kW motor-operated 0.9pf.
kVAR = 7.5 x tan (cos-1(pf))
= 7.5 x tan (cos-1(0.9))
= 7.5 x tan (25.84193276)
= 7.5 x 0.4843221
= 3.6kVAR
