The power factor correction is a technique of increasing the power factor of a power supply. Switching power supplies without power factor correction draw current in short, high-magnitude pulses. Displacement PF is defined as the cosine of the angle between fundamental voltage and fundamental current of the load. The presence of Harmonics increases the RMS current and voltage relative to their respective fundamental values. This increases the KVA of the Load. The Power Factor correction capacitor taking into account the effect of the Harmonics is called the true power factor..
True PF ≤ Displacement of the factor by which Displacement PF is related to the True PF is called the Distortion PF
What is Power Factor Correction Capacitor
The power factor of your installations can be improved by the placement of power factor capacitors where they work as reactive generators of power.
