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.
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 neutralizing the magnetic current, capacitors help to cut losses in the electrical distribution system and reduce electricity bills.
Capacitor Leakage Power Factor is the ratio of the active power to the apparent power, and it is an important factor in calculating electricity consumption. It is an automatic power factor control panel, which corrects the power factor by switching on/off the necessary units of capacitor banks.
Conversely, if a circuit is predominantly capacitive, we say that its power factor is leading. Thus, our example circuit started out with a power factor of 0.705 lagging and was corrected to a power factor of 0.999 lagging. REVIEW:
For power factor correction, the capacitor bank is used to connect with the load. If the load is a three-phase load, the capacitor bank can be connected as a star and delta connection. The below circuit diagram shows delta connected capacitor bank with a three-phase load.
The impedance for a circuit with a power factor compensation capacitor is given by Equation 5, where XC is capacitive reactance and is given by Equation 6. In most industries, a system of capacitors controlled by a power factor correction controller is installed for reactive power compensation.
