Many loads are mainly resistive; thus, they’re rated in watts (i.e., true power). Simply stated, these loads have a very small reactive component, which means an apparent power rating (VA) would not ...

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 ...

Fundamentally, electrical power is developed, delivered, and consumed as voltage and current. In a simple direct current (DC) device such as a flashlight, the power (the brightness of the bulb) is 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 ...

In its latest monthly column for pv magazine, IEA-PVPS provides a comprehensive overview of the state-of-the-art practices, best practices, and recommendations for managing reactive power amidst the ...
