POWER FACTOR CORRECTION – Applied Industrial Electricity
Since we know that the (uncorrected) reactive power is 119.998 VAR (inductive), we need to calculate the correct capacitor size to produce the same quantity of (capacitive) reactive power. Since this capacitor will be directly in parallel with the source (of known voltage), we''ll use the power formula which starts from voltage and reactance:
