The Effects of Low Power Factor on Electrical Equipment
The cosine of the angle between voltage and current in an AC circuit is referred to as the power factor. In a typical AC circuit, there is a phase difference Φ between the voltage and current. The term cos Φ is termed to as the power factor of the circuit; if the current is inductive,…

How to calculate the Power Factor Correction
Let us consider an inductive load taking a lagging current I at a power factor cosΦ1. For us to improve the power factor of such a circuit, the solution is to connect equipment in parallel with the load which takes a leading reactive component and partly cancels the lagging reactive component of the load. Figure…
