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 ...

A large-scale power grid’s ability to transfer energy from producers to consumers is constrained by both the network structure and the nonlinear physics of power flow. Violations of these constraints ...

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 ...
