APFC Panel

Smart Power Management. Maximum Efficiency. Regulatory Compliance.

At Greenventum, we engineer high-performance Automatic Power Factor Correction (APFC) Panels that enable industries and commercial facilities to optimize power usage, reduce energy losses, and eliminate power factor penalties. Our APFC systems intelligently manage reactive power and ensure that your electrical network operates at its highest efficiency and lowest cost.

In an era where energy efficiency is directly linked to profitability and sustainability, APFC Panels are not just a technical upgrade—they are a strategic necessity.

What is an APFC Panel?

An Automatic Power Factor Correction Panel is an electrical control panel that uses microprocessor-based relay logic to monitor the power factor in real time and switch capacitor banks automatically as per load requirements. It improves the power factor to near unity (0.99–1.0), thereby minimizing apparent power drawn, less equipment & cable heating  and reducing electricity bills.

Types of APFC Panels Offered

  1. Conventional APFC Panels
    – Step-based capacitor switching using contactors, suitable for stable and moderately varying loads.
  2. Thyristorized (Detuned) APFC Panels
    – Rapid switching using thyristors (SCRs) for dynamic and highly fluctuating loads, like welding, CNC, load presses,cranes and elevators.
  3. Real-Time/Hybrid APFC Systems
    – Combines the speed of thyristor modules with the cost-efficiency of contactors. Ideal for mixed-load applications.
  4. Detuned APFC Panels with Reactors
    – Equipped with series reactors (typically 7% detuning) to prevent harmonic resonance and increase capacitor life.

Key Benefits of APFC Panels

  • Eliminates Power Factor Penalty
    Reduces electricity bills by avoiding penalties imposed by utilities for low power factor (<0.9).
  • Optimizes Transformer & Cable Loading
    Improves system capacity and reduces I²R losses by minimizing reactive power drawn.
  • Improves System Voltage & Stability
    Better voltage regulation enhances the lifespan and efficiency of electrical equipment.
  • Protects Against Harmonics (in Detuned Systems)
    Avoids harmonic amplification and capacitor burnout, especially in VFD-driven systems.
  • Enables Regulatory Compliance
    Meets requirements under Electricity Supply Codes, DISCOM norms, and Green Building Codes.
  • Fast ROI
    Typical payback period ranges from 6 to 18 months, depending on load profile and tariff structure.
