HP to kVAR Calculation

Reactive power Q(kVAR) in Kilo volt amp reactive is equal to 0.746 times of real power P(HP) in horsepower and the tan of power angle (φ). Hence for converting HP to kVAR, the formula can be written as,

Q(kVAR) = 0.746 x P(HP) x tan(φ)

Or

Q(kVAR) = 0.746 x P(HP) x tan(cos-1(pf))

Example:

Calculate the reactive power in kVAR for the 1 HP motor is running at 0.86 power factor.

kVAR = 0.746 x 1 x tan(cos-1(0.86))

Reactive power = 0.746 x 1 x 0.59336515

 = 0.44 kVAR.

Hence 1 HP motor consumes 0.44kVAR while operating it in 0.86pf.
