Ideally, the power factor should be 1; then the load appears as a resistor to the AC source. However, in the real world, electrical loads not only cause distortions in AC current waveforms, but also ...

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.

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 ...

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 ...

If you operate electric motors in your manufacturing facility, you may be paying for wasted power. The power factor of your electrical system gives the amount of productive power your facility is ...
