An Automatic Power Factor Correction (APFC) panel is a crucial device used to enhance the power factor of an electrical system. Let’s explore its key features:

 

1. Power Factor Improvement:
   • The APFC panel automatically adjusts the phase angle between voltage and current.
   • This results in a lower power factor, which is essential for efficient energy utilization.
2. Microcontroller-Based Operation:
   • The APFC unit contains a microcontroller that detects the power factor value.
   • If the power factor drops below 0.9 (lagging) during peak hours, the panel connects capacitor banks to improve it.
3. Significance:
   • APFC panels are crucial in industries with large electrical loads.
   • They prevent operational utility energy losses and potential penalties from electricity boards.
