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.
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.
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.
A fixed power factor capacitor bank can be switched on when the inductive load is on, and off when the individual load is off. Such capacitors are energized only when power factor correction is needed. In facilities with multiple loads, load conditions and power factor correction needs change frequently.
Benefits of Using Capacitor Banks: Employing capacitor banks leads to improved power efficiency, reduced utility charges, and enhanced voltage regulation. Practical Applications: Capacitor banks are integral in applications requiring stable and efficient power supply, such as in industrial settings and electrical substations.
Capacitor Bank Definition: A capacitor bank is a collection of multiple capacitors used to store electrical energy and enhance the functionality of electrical power systems.
