The power factor indicates how efficiently energy is drawn from the AC source. With a poor power factor, a utility needs to generate more current than the electrical load actually needs, which causes ...

Calculating Power Factor. Source: CAS Data Loggers Most discussions on manufacturing energy efficiency focus on identifying easy-to-find-and-fix energy wasters such as compressed air leaks, ...

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.
