An example of how to calculate the capacity of reactive power (kVAr)? An Motor is supplying a load of 700 kW at a P.F (Power factor) of 0.65. What size of Capacitor in kVAr is required to raise the P.F (Power Factor) to unity (1)? And how many more kW can the motor supply for the same kVA loading when P.F improved. Supplying kW = 700 kW Original P.F = Cosθ1 = 0.65 Final P.F = Cosθ2 = 1 θ1 = C...

Benefits by installing power factor correction systems? Power factor correction systems provide much benefit: Reduced electricity utility bills Your electric utility provides working (kW) and reactive power (kVAR) to your plant in the form of apparent power (kVA). While reactive power (kVAR) doesn’t register on kW demand or kW hour meters, the utility’s transmission and distribution system must be...
