Capacitor Banks for Power Factor Correction

What are Capacitor Banks?

A capacitor bank connects multiple capacitors together to store and release electrical energy. This is to enhance power quality and efficiency in electrical systems. It achieves this by providing power factor correction and reactive power compensation. They can be connected in parallel or series, actively stabilizing voltage levels, minimizing energy losses, and significantly improving the overall performance of electrical networks.

Why use capacitor banks?

Companies use capacitor banks for several compelling reasons. They employ them to correct power factor to help maintain the power factor. this reduces energy losses and improves overall system efficiency. It can also enhance voltage stability by actively providing reactive power, especially during peak demand. Additionally, the banks actively store and release electrical energy for power backup or energy smoothing.

What is TNB Power Factor Penalty?

TNB (Tenaga Nasional Berhad) imposes a power factor penalty when the power factor falls below the specified threshold. This penalty is calculated based on the current bill and the deviation from the required power factor. Maintaining a high power factor is essential for efficient electricity usage and minimizing system losses. To avoid penalties and improve power factor, TNB advises customers to install capacitors banks.
