The required capacitor output may be calculated as follows:
  • Determine the factor "k" by matching the point where actual and target power factor intersect.
  • Calculate the required capacitor rating with the formula Qc =k x P
    Example

    Actual power factor = 0.70, Target power factor = 0.96, Real power (P) = 35kW

    Capacitor output (Qc) = k x P
                                    = 0.73 x 35kW
                              Qc   = 25.5 kVAr
