The unit for rating power factor capacitors is a kVAR, equal to 1000 volt-amperes of reactive power. The kVAR rating signifies how much reactive power the capacitor will provide.

Sizing capacitors for individual motor loads

To size capacitors for individual motor loads, use Table 3 on the following page. Simply look up the type of motor frame, RPM, and horsepower. The charts indicate the kVAR rating you need to bring power factor to 95%. The charts also indicate how much current is reduced when capacitors are installed.

Sizing capacitors for entire plant loads

If you know the total kW consumption of your plant, its present power factor, and the power factor you’re aiming for, you can contact with us.
