Power factor

Power factor is an expression of energy efficiency. It is usually expressed as a percentage—and the lower the percentage, the less efficient power usage is. Power factor (PF) is the ratio of working power, measured in kilowatts (kW), to apparent power, measured in kilovolt amperes (kVA) Power Factor. In AC circuits, the power factor is the ratio of the real power that is used to do work and the apparent power that is supplied to the circuit. The power factor can get values in the range from 0 to 1. When all the power is reactive power with no real power (usually inductive load) - the power factor is 0 Power Factor Explained. In this tutorial we look at power factor. We'll learn what is power factor, what is good and bad power factor, how to compare power factor, the causes of power factor, why and how to fix power factor as well as some example calculations to help you learn electrical engineering Need for Power Factor Improvement. Real power is given by P = VIcosφ. The electrical current is inversely proportional to cosφ for transferring a given amount of power at a certain voltage.Hence higher the pf lower will be the current flowing

Power Factor can also be represented by thinking of a simple clock face, where a PF of 1 is represented by 12 o'clock. A PF of 0 can be either side of 12, either at 9 or 3 o'clock (depending on which way the kVArs are flowing in reference to the kW) Power Factor Definitions and Formulas. In electrical engineering, power factor is only and only related to AC circuits i.e. there is no power factor (P.f) in DC circuits due to zero frequency and phase angle difference (Φ) between current and voltage Power factor can be an important aspect to consider in an AC circuit because of any power factor less than 1 means that the circuit's wiring has to carry more current than what would be necessary with zero reactance in the circuit to deliver the same amount of (true) power to the resistive load

Power Factor (PF) in practical shooting competitions refers to a ranking system used to reward cartridges with more recoil.Power factor is a measure of the momentum of the bullet (scaled product of the bullet's mass and velocity), which to some degree reflect the recoil impulse from the firearm onto the shooter (see section on limitations).. A high power factor allows efficient use of energy, while a low power factor indicates poor utilization of electrical power. Each equipment or load has its own power factor and depends on the resistive or inductive load, some typical or common values for buildings, appliances and motors are shown below Power factor is unity (i.e. 1) for ideal circuits. When current and voltage are in phase, PF = 1; Power factor cannot be more than unity. Practically, it should be as close to unity as possible. If power factor is low, following problems are encountered: Effects of low power factor. Load Current Power in an AC circuit can be given as: P = VI cos Power factor improvement aims at optimal utilization of electrical power, reduction of electricity bills and reduction of power loss. Power transformers are independent of P.F. If the power factor is close to unity, for the same KVA rating of the transformer more load can be connected. (Better the power factor lesser will be the current flow)

Power factor is defined as the cosine of angle between the voltage phasor and current phasor in an AC circuit. It is denoted as pf. For an AC circuit, 0≤pf≤1 whereas for DC circuit power factor is always 1.
