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. Power Factor Correction: Power factor correction involves adjusting the capacitor bank to optimize the use of electricity, thereby improving the efficiency and reducing costs.
By reducing the circulating current caused by inductive loads within a circuit, capacitor banks increase efficiency, decrease energy costs, and extend the life span of electrical systems and substations. Furthermore, capacitor banks are necessary for compensating reactive power in order to steady voltage fluctuations within a power system.
Therefore, to improve system efficiency and power factor, capacitor banks are used, which lessen the system’s inductive effect by reducing lag in current. This, ultimately, raises the power factor. So, we can say that capacitor banks reduce power losses by improving or correcting the power factor. They are commonly used for these three reasons:
Connecting the capacitor bank across the line helps absorb part of the reactive power drawn by these loads, resulting in improved power factor and therefore better efficiency in your power system.
By using a capacitor bank, the power factor can be maintained near to unity. Improving power factor is the process of reducing the phase difference between voltage and current. Basically capacitor banks reduce the phase difference between the voltage and current.
Capacitor bank is used for reactive power compensation and power factor correction in the electrical substation.
