The scope of this article is to introduce a method to measure the power factor in a 50 Hz alternating current transient. The circuit shall be a R-L type. By acquiring only the current wave and, ...

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 ...

There are many discussions regarding PUE (power usage effectiveness) nowadays. While more and more people want to at least have an idea of what PUE they are running at, there are quite a few who think ...

The meters installed on the premises of the micro units to calculate electricity consumption charges do not have provision to calculate reactive power and hence power factor cannot be calculated based ...

Oscilloscopes measure current and voltage and, through the magic of mathematics, calculate power. Unfortunately, power comes in a large number of guises: instantaneous, real, apparent, and reactive.

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 ...

One “component” in the quest for improved energy efficiency and power quality is the use of active harmonic filter power factor correction (PFC) in switched-mode power supplies (SMPSs) for computing ...

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 ...
