Power factor correction uses parallel connected capacitors to oppose the effects of inductive elements and reduce the phase shift between the voltage and current. Power factor correction is a ...

Inverters are looked at by power utilities as “static” devices since they are not of the type classified as rotating machinery such as electric generators. The power companies require users, who put ...

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 ...

Correctly installing capacitors at the terminals of your motors can lower reactive power requirements and increase system power factor. Induction motors are the primary source of rotary power in the ...

We have a number of recognized transmission and distribution experts serving on our board of "Grid Masters." Several times each month we’ll post what we judge to be the toughest questions that also ...

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

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 ...

Capacitive wireless-power-transfer technology has the potential to overcome the power, distance, and orientation limitations of inductive power-transfer systems, such as Qi technology. Comparing ...

Wind generation system is becoming increasingly important as renewable energy sources due to its advantages such as low maintenance requirement and mainly it does not cause environmental contamination ...
