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 ...

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 ...

Power factor (pf) is the ratio between real power (P) flowing to the load, and the apparent power (S) in the circuit: pf = P/S. It is a sinusoidal waveform and therefore expressed as a dimensionless ...

So-called “Power Saver Devices” (known by different names) are nothing but Power Factor Correction (PFC) devices that would connect to the mains and improve power factor measured by your electricity ...

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 ...

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 ...

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 ...
