Maintaining Target Power Factor Under Fluctuating Load Conditions

Fluctuating loads are a common challenge in many industries. Rapid changes in current demand can make it difficult for standard APFC panels to maintain a stable and high power factor.

When an APFC controller is not designed for dynamic loads, the result is often:

Low monthly average power factor (e.g., 0.82)

• High electricity bills due to heavy PF penalties (e.g., ₹78,541)
• A poor average PF directly increases your energy cost and reduces system efficiency.

Lauritz Knudsen offers two advanced thyristor-based APFC controllers specifically designed for fluctuating load conditions:

• etaSMART T – Single CT APFC Controller
• etaULTRA T – Three CT APFC Controller

Both controllers are built for thyristor switched APFC panels, enabling fast and accurate capacitor switching even when loads are rapidly changing.

These smart controllers ensure a significant improvement in monthly average power factor, helping you avoid penalties and reduce electricity bills.

If your facility experiences fluctuating loads, upgrading to a thyristor-based APFC system with etaSMART T or etaULTRA T is a smart investment.

Takeaway: Don’t let fluctuating loads ruin your power factor. Choose the right controller and maintain a high, stable PF every month.
