What is Capacitor Bank?

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.

Capacitor Bank Classification

• Shunt Capacitor Banks

Advantages

• Simple, cheap, and easy to install and maintain.

• Provide more flexibility and accuracy in reactive power control.

• Improve voltage stability

Disadvantages

• Cause overvoltage or resonance problems

• May introduce harmonics

• May not be effective for long transmission lines

• Series Capacitor Banks

Advantages

• Power transfer efficiency

• Reduce the short-circuit current

• Improve the transient response

Disadvantages

• May cause overvoltage

• May introduce harmonics

• May not be effective for low voltage

Benefits of Using Capacitor Banks

Employing capacitor banks leads to improved power efficiency, reduced utility charges, and enhanced voltage.
