May 2019 – The Importance of Power Factor Correction
Published on: 31/05/2019
A good power factor is becoming increasingly important today because more devices are fitted with switch-mode power supplies
Equipment fitted with switch-mode power supplies can often present a non-linear load and create harmonics that could potentially cause damage, lower efficiency and increase running costs.
Power Factor Correction
In an ideal situation, the voltage and current would be in phase so that the device consumed all the power it drew and the PF was 1.0. Power Factor is best described as the ratio of the actual electrical power dissipated by an AC circuit, PF values can range from 0 to 1. When all the power is reactive power with no real power (usually an inductive load) the power factor is 0 which is when a power factor correction device is required.
Power factor correction is an adjustment of the electrical circuit in order to change the power factor to as close to 1 as possible. Increased power factor reduces the reactive power in the circuit and most of the power in the circuit will be real power, reducing power line losses.
