Capacitors store electrical energy temporarily and release it when needed. In the context of power factor correction, this means that when devices like motors and transformers draw a current that lags the voltage, the capacitors will cancel out the lag with the leading current, thus improving the power factor. Types of Capacitors Used in Power

To understand power factor, we''ll first start with the definition of some basic terms: KW is Working Power (also called Actual Power or Active Power or Real Power). It is the power that actually powers the equipment and performs useful work. KVAR is Reactive Power. It is the power that magnetic equipment (transformer, motor and relay)
The working principle of a capacitor revolves around the accumulation and retention of electric charge between two conductive plates separated by a non-conductive material. This simple yet ingenious design
Since capacitors have a leading power factor, and reactive power is not a constant power, designing a capacitor bank must consider different reactive power needs. For example, the configuration for a 5-stage capacitor bank with a 170 KVAR maximum reactive power rating could be 1:1:1:1:1, meaning 5*34 KVAR or 1:2:2:4:8 with 1 as 10 KVAR.

A Power Capacitor is an electrical device that can store and discharge electric energy. The device consists of one or more pairs of plates, separated by an insulating material (the dielectric), which are attached to two terminals that allow the stored energy to be discharged into a circuit when required. The power capacitor symbol is shown below.
This post provides deeper look into capacitor based power factor correction circuits and power factor correction (PFC) capacitors. Some of the AC power consumed by inductive loads is used to maintain magnetic reversals due to phase shift between current and voltage.
A capacitor helps to improve the power factor by relieving the supply line of the reactive power. The capacitor achieves this by storing the magnetic reversal energy. Figure 7 shows an inductive load with a power factor correction capacitor. Figure 8 above illustrates the improvement in power factor when the capacitor is added to the circuit.
Parallel capacitors or phase shift capacitors are generally used to compensate for the inductive load's reactive power within the power system so that the power factor can be increased, line loss can be decreased and voltage quality can be enhanced. Series capacitors are used in high voltage systems to compensate for the power systems' reactance.
The more energy that's stored, the faster it can discharge into another load. The specifications of a power capacitor mainly include WVDC (working DC voltage), WVAC (working AC voltage), power rating, rated current, temperature coefficient, insulation resistance, and dissipation factor and each specification is discussed below.
Although power factor correction capacitors can considerably reduce the burden caused by an inductive load on the supply, they do not affect the operation of the load. By neutralising the magnetic current, capacitors help to cut losses in the electrical distribution system and reduce electricity bills.
