APFC Panel

What is an APFC Panel?

An Automatic Power Factor Control (APFC) Panel is designed to improve power factor in electrical systems by automatically switching capacitor banks on or off depending on the load conditions.

How it is Used?

It continuously monitors the power factor of the electrical system and uses contactors or thyristor modules to switch capacitor banks, ensuring the power factor stays within permissible limits.

Where it is Used?

• Manufacturing plants
  
  
• Steel, cement, and textile industries
  
  
• Commercial complexes
  
  
• Power-intensive facilities with fluctuating loads
