Active power factor correction can achieve very high power factors—0.98 and above—with reasonably sized components, though the energy efficiency may be slightly lower than with passive techniques (94 ...

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 ...

Why is Power Factor important? The phase relationship between the ac-power-line voltage and current is related by a term called power factor. For a purely resistive load on the power line, voltage and ...

video: Business and industry love squirrel cage induction motors for high speed applications. Power grid Managers detest them, because their power factors under low loads can make a grid unstable. But ...

When a large motor (or critical one) fails, a postmortem of the motor is never a bad idea. It should be standard operating practice. But while that work is being done at the motor shop, what about the ...

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 ...

How often are homeowners approached by a salesperson at the doorstep selling a device that can go in a wall and supposedly save energy or reduce the monthly electricity bill substantially? The ...

The developer, Power Efficiency Corp. in Las Vegas, says the technology is an improvement on a three-phase power factor controller developed by NASA engineer Frank Nola in the 1970s. Power Efficiency ...

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 ...

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 ...
