Power Factor (PF) is a measure of how a load draws power from the source. When the current phasor leads the voltage phasor, PF is leading and when the current phasor lags the voltage phasor, PF is ...

As the push to move beyond the easy-to-find sources of energy inefficiencies intensifies, a key area to investigate is the power factor of your facility and the impact your automation devices have on ...

(Editor's Note: Since this article appeared online, a reader submitted some interesting comments, and there was a response to those comments as well. Scroll down, below the “About the author” section, ...

Providing modern electronic devices with a diet of healthy power is not straightforward. Small AC-connected equipment often uses a capacitor-input filter following a half- or full-wave rectifier.

New capacitors place additional demands on contactors to keep power circuits balanced. • Electrical power sources supply two types of power to inductive loads: real power in kW and reactive power in ...

Most modern industrial facilities have widespread applications of nonlinear loads, many of which represent a significant portion of the total facility load. As a result, they can inject harmonic ...

It hasn’t been that long since humans figured out how to create power grids that integrated multiple generators and consumers. Ever since AC won the battle of the currents, grid operators have had to ...

High-brightness LEDs are an inexpensive, robust, and green replacement for halogen light bulbs. This Idea for Design shows you how to apply an AC LED driver to convert the usual 12 or 24 V AC ...
