What is a Capacitor Bank Used for?

  • Capacitor banks are used to compensate for reactive power, that is, to correct the power factor in alternating voltage systems, which leads to energy savings, greater energy efficiency, and prevention of premature wear of electrical equipment.
  • The capacitor bank is connected in parallel with the power line and is designed to store electrical energy at a greater capacity than an individual capacitor.

Advantages of a Capacitor Bank

Capacitor banks improve energy efficiency and electrical system reliability, resulting in significant long-term savings.

  • Power factor improvement.
  • Reduction of heating losses.
  • Improved voltage regulation.
  • They support reducing service interruptions.
  • Freeing up capacity in the system.
  • Compliance with the grid code.
  • Energy saving

Types of Capacitors: Fixed and Automatic

  • A fixed capacitor bank has a predetermined number of capacitors that are manually connected or disconnected according to the needs of the electrical system.
  • On the other hand, an automatic capacitor bank uses a control system that automatically detects and corrects the power factor, connecting and disconnecting capacitors based on the system's needs in real time. It requires less supervision and maintenance than a fixed capacitor bank.
  • We also have high voltage capacitor banks.

Applications of Fixed Capacitor Banks in Electrical Systems

They can be applied in power distribution systems, lighting, motors and other electrical equipment.
