    AI Overview
    A low voltage Automatic Power Factor Correction (APFC) panel is an electrical board that automatically monitors and corrects a system's power factor by switching capacitor banks in and out in real-time. It reduces reactive power, eliminates penalty charges, improves energy efficiency by up to 30%, and maintains a power factor close to unity. 
    Key Features and Components 
    • Automatic Controller: A microprocessor-based relay monitors the system's power factor using current transformers (CT). 
    • Capacitor Banks: These are used to inject leading reactive power to neutralize lagging power from inductive loads. 
    • Switching Components: Typically includes capacitor duty contactors or solid-state switches (thyristors) to connect/disconnect capacitor steps. 
    • Protection Devices: Incorporates MCCBs (Molded Case Circuit Breakers) or MCBs (Miniature Circuit Breakers) to protect against overloads and short circuits. 
    • Optional Harmonic Filters: Some panels, often termed Active Power Filters (APF), use passive or active, detuned reactors to filter out harmful harmonics. 
    Benefits of Low Voltage APFC Panels 
    • Reduced Power Costs: Eliminates electricity board penalties for low power factor, often leading to lower KVA demand charges.
    • Optimal Efficiency: Maintains a high power factor (e.g., >0.99 or unity).
    • Increased System Capacity: Reduces voltage drop and lowers the current drawn from the main supply.
    • Longer Equipment Life: Reduces thermal stress on cables and transformers. 
    Common Applications 
    • Large manufacturing, chemical, cement, and paper industries.
    • Commercial buildings, malls, and hospitals.
    • Substations with fluctuating inductive loads. 
    These panels are commonly used for 3-phase AC, 50/60 Hz systems, operating at voltages up to 690V.

    What is a low-voltage panel?
    A low voltage panel – also known as an LV distribution board or electrical switchboard – is a critical component in electrical distribution systems. It serves as the centralized point that receives electrical power (typically under 1000V) and distributes it to various circuits or equipment throughout a facility.Apr 25, 2025

    What are the disadvantages of PFC?
    Disadvantages of Passive PFC:

    Fixed compensation (not ideal for rapidly changing loads). Risk of overvoltage/resonance (if not properly tuned). Cannot correct leading PF (only compensates lagging PF).

    What happens if power factor is too low?
    Increased Energy Losses: A poor power factor causes a higher current flow for the same amount of useful power that is delivered. This results in increased energy losses.
