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 ...

Motors and generators are critical components of electrical systems. They are used to automate numerous industrial processes, circulate liquids for cooling and lubrication purposes, and generate ...

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 ...

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 ...

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 ...

1. Power-factor triangle relates the real power, the reactive power, and the apparent power. (Courtesy of Vector Group) Let’s start by talking about the concept of power factor (PF). Assuming ...
