Power Factor Correction (PFC) Handbook
Power factor correction is simply defined as the ratio of real power to apparent power or: PF RealPower ApparentPower where the real power is the average over a cycle of the instantaneous product of current and voltage and the apparent power is the product of the rms value of current times the rms value of voltage If both current and voltage |

Rick Orman Americas Sales Manager Power Factor Correction/Surge Protection/Power Conditioning Power factor definition • Power factor is the ratio between the kVA kVAr “real” power and the φ “apparent” power of an kW electrical system “Real” power = working power = kW “Apparent” power = Volts x Amps = kVA “Reactive” power = magnetizing power = kVAR |

Power factor correction: a guide for the plant engineer
Power factor clause: Rates based on power factor of 90 or higher When power factor is less than 85 the demand will be increased 1 for each 1 that the power factor is below 90 If the power factor is higher than 95 the demand will be decreased 1 for each 1 that the power factor is above 90 |

POWERFACTOR CORRECTION (pfc)
The benefits that can be achieved by applying the correct power factor correction are: Environmental benefit Reduction of power consumption due to improved energy efficiency Reduced power consumption means less greenhouse gas emissions and fossil fuel depletion by power |
What is power factor correction (PFC)?
The ratio between real, usable power (measured in watts) and the total real-plus-reactive power is known as the power factor. A power factor correction (PFC) circuit intentionally shapes the input current to be in phase with the instantaneous line voltage and minimizes the total apparent power consumed.
Do power factor correction capacitors increase current-carrying capacity?
Power factor correction capacitors increase system current-carrying capacity . Raising the power factor on a kW load reduces kVA . Therefore, by adding capacitors, you can add additional kW load to your system without altering the kVA . Figure 8. Correcting Power Factor Increases Transformer Output
Which topology is used for active power factor correction?
The boost (or step-up) converter is the most popular topology for active power factor correction. With the proper control, it can be made to produce a constant output voltage while drawing a sinusoidal current from the line. Figure 1. Active PFC Stage with the NCP1606
How do you know if a power factor correction capacitor is bad?
• If the plant contains power factor correction capacitors, the current into the capacitors should be measured using a “true rms” current meter . If this value is higher than the capacitor’s rated current at the system voltage (by >5% or so), the presence of harmonic voltage distortion is likely
Why improve power factor ?
The benefits that can be achieved by applying the correct power factor correction are: Environmental benefit. Reduction of power consumption due to improved energy efficiency. Reduced power consumption means less greenhouse gas emissions and fossil fuel depletion by power electrical.theiet.org

How to improve power factor
Power factor correction is achieved by the addition of capacitors in parallel with the connected motor or lighting circuits and can be applied at the equipment, distribution board or at the origin of the installation. Static power factor correction can be applied at each individual motor by connecting the correction capacitors to the motor starter
