Power Factor Improvement (PFI) System – Capacitor Bank Panel (5 kVAr to 1000+ kVAr) | Integrated Power & Engineering
At Integrated Power & Engineering, we deliver Power Factor Improvement (PFI) Systems designed to enhance the efficiency of electrical networks by correcting low power factor in industrial and commercial installations. Our PFI solutions help reduce reactive power demand, improve voltage stability, minimize system losses, and support compliance with utility requirements—making them an essential part of modern power infrastructure.
Poor power factor increases current flow, creates extra heat in cables and transformers, and often results in higher electricity costs and utility penalties. With a properly engineered PFI capacitor bank panel, your facility can maintain an optimal power factor, reduce operating expenses, and improve overall equipment performance.
Product Overview: What is a PFI System?
A PFI system improves power factor by adding capacitor banks to compensate reactive power generated by inductive loads such as motors, compressors, welding machines, chillers, elevators, and HVAC systems. By reducing unnecessary reactive current, the electrical system becomes more efficient—freeing up transformer capacity, reducing voltage drop, and improving overall stability.
Integrated Power & Engineering provides Manual PFI and Automatic PFI systems engineered as per your site load profile and correction target.

FAQs (Frequently Asked Questions)
1) How do I know if my facility needs a PFI system?
If your power factor is frequently low (especially in facilities with motors, HVAC, pumps, compressors, welding machines), you may face higher losses and possible utility penalties. A site measurement or monthly bill review can indicate whether a PFI system is needed.
2) What is the difference between Manual PFI and Automatic PFI?
Manual PFI uses fixed capacitor steps that are switched manually, suitable for stable loads. Automatic PFI uses a relay to switch capacitor steps automatically based on changing load conditions, making it better for fluctuating industrial/commercial loads.
3) How is the required kVAr size selected?
kVAr sizing is based on your load profile, present power factor, target power factor, and transformer/feeder capacity. A proper load study helps select the correct total kVAr and step configuration for stable correction.
4) What power factor target is usually recommended?
The ideal target depends on utility requirements and site conditions. Many facilities aim for a near-unity range to reduce losses and penalties while maintaining stable operation. We design the system to match your compliance and efficiency goals.
5) Can a PFI system reduce electricity bills?
Yes. By reducing reactive power flow and improving system efficiency, PFI can lower losses and help avoid penalty charges (where applicable). It can also free up capacity in transformers and cables, improving overall performance.
6) Is PFI safe for sensitive equipment and electrical networks?
Yes, when designed correctly. Our systems include safe discharge resistors, protection options, and proper step design to ensure stable correction and safe operation within the electrical network.
7) Can PFI panels be expanded later?
Yes. Our PFI panels are modular and scalable. You can increase kVAr capacity or modify step configuration if your load grows or new equipment is added in the future.
8) Do you provide installation, commissioning, and maintenance support in Bangladesh?
Yes. Integrated Power & Engineering provides end-to-end support including design, manufacturing, testing, installation guidance, commissioning assistance, and after-sales maintenance support locally.
