Effect of power factor
WebJan 13, 2015 · Measuring the Power Factor Power factor (PF) is measured between 0 and 1.0 (usually given as a percentage, with 100 percent or 1.0 being unity). ... For example, … WebThe poor power factor in an AC circuit may be “corrected”, or re-established at a value close to 1, by adding a parallel reactance opposite the effect of the load’s reactance. If the load’s reactance is inductive in nature (which is almost always will be), parallel capacitance is what is needed to correct poor power factor.
