The size of capacitor in kVAR is the kW multiplied by factor in table to improve from existing power factor to proposed power factor. Check the others solved examples below. Example 2: An Alternator is supplying a load of 650 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)?
For P.F Correction The following power factor correction chart can be used to easily find the right size of capacitor bank for desired power factor improvement. For example, if you need to improve the existing power factor from 0.6 to 0.98, just look at the multiplier for both figures in the table which is 1.030.
Required Capacitor kVAR to improve P.F from 0.75 to 0.90 Required Capacitor kVAR = P (Tan θ1 – Tan θ2) = 5kW (0.8819 – 0.4843) = 1.99 kVAR And Rating of Capacitors connected in each Phase 1.99 kVAR / 3 = 0.663 kVAR Note: Tables for Capacitor Sizing in kVAr and microfarads for PF Correction
Multiply this number with the existing active power in kW. You can find the real power by multiplying the voltage to the current and the existing lagging power factor i.e. P in Watts = Voltage in volts x Current in Amps x Cosθ1. This easy way, you will find the required value of capacitance in kVAR which is needed to get the desired power factor.
