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 ...

Recent studies indicate the level of knowledge and implementation of motor system energy-efficiency measures is low. A plethora of information on motor system design, best practices, purchasing, and ...

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 ...

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 ...

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 ...

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 ...

Your utility Power Factor is the ratio of the system’s Real Power and the Apparent Power (Eq. 1, Fig. 1). This unitless factor ranges from −1 to 1. The Power Factor ratio aptly describes the type of ...
