    Power Factor Correction Law

    Power Factor Correction (PFC) boosts electrical system power factor through the reduction of reactive power and improvement of efficiency. Multiple laws and principles regulate the operation of Power Factor Correction (PFC).

    Steps to Calculate Capacitance for Power Factor Correction:

    Find the required reactive power (Qc):

    Required Reactive (QC) = P × [tan(cos-1θ1) - tan(cos-1θ2)]

    For Single Phase:

    For 1-phase Power Factor Correction, the required capacitance (C) can be calculated using the formula:

    C = Qc2 × 𝜋 × f × V2

      Where:

    • C = Required capacitance (Farads)
    • Qc = Required reactive power (VAR)
    • V = Voltage (Volts)
    • f = Frequency (Hz)
    • 𝜋 = 3.1416 (constant)

    For 3 phase AC circuits for Phase to Voltage:

    First we have to convert the given power factors into angle using formula Phase to Voltage for 3 Phase:

    C = Qc2 × 𝜋 × f × (Vph)2

    For 3 phase AC circuits for Line to Line Voltage:

    First we have to convert the given power factors into angle using formula Line to Line Voltage for 3 Phase:

    C = Qc2 × 𝜋 × f × (VL ÷ √3)2
