Power factor correction is a frequently misunderstood topic. Improper techniques can result in over-correction, under-correction, and/or harmonic resonance, so it can be helpful to understand the ...

I’m sure many readers would question why anyone would want to perform a relatively expensive insulation power factor test on an inexpensive transformer. Typically, if any testing is done, it will be ...

Power factor (pf) is the ratio between real power (P) flowing to the load, and the apparent power (S) in the circuit: pf = P/S. It is a sinusoidal waveform and therefore expressed as a dimensionless ...

Power factor correction uses parallel connected capacitors to oppose the effects of inductive elements and reduce the phase shift between the voltage and current. Power factor correction is a ...

Low power factor reduces an electrical system’s distribution capacity by increasing current flow. Therefore, having a low power factor is inefficient and expensive. But what is power factor and what ...

Electric motor power efficiency has taken center stage. Individuals, corporations, and governments are increasingly interested in saving power, now that technology can make it possible and economy ...

The phrase power factor frequently is used in the electrical and power electronics industry. For example, home, office, and industrial electrical equipment often is fitted with power factor-corrected ...

Most discussions on manufacturing energy efficiency focus on identifying easy-to-find-and-fix energy wasters such as compressed air leaks, inefficient lighting, equipment that is always left on when ...

The power factor measurement has long been accepted as an invaluable tool for identifying insulation defects, such as ageing, deterioration, moisture ingress and localized failures, involving the ...
