Power control and energy management systems (PCS and EMS) are powerful tools that will enable the next generation of electrical systems, and the way they are featured in the 2026 NEC is a testament to ...

Providing modern electronic devices with a diet of healthy power is not straightforward. Small AC-connected equipment often uses a capacitor-input filter following a half- or full-wave rectifier.

The electrical panel, also known as the service panel, is the control center for all the electrical circuitry in a residence. Today's panels are bigger than earlier versions. They have to be, because ...

Motivation for Research: The constant evolution of the electric grid with the integration of generation from renewable sources and “smart” components makes peak electric load management an essential ...

Last month in Code Basics, “Commercial Loads — Part 1,” on page 24 of the January issue, we discussed when it’s okay to apply demand factors when calculating ...

Here is a simple method for estimating the actual load on an electric motor without special equipment. But first, a word of caution: Some applications (e.g., a large forced draft fan) require more ...

The aim of this project is to control the electrical appliances through a personal computer (PC). For example, theatre lighting can be centrally controlled form the PC for better stage management. The ...

It used to be when you turned the vehicle off, all electrical loads went away. Now that today's trucks use electronics full time, including the extra hotel loads for driver comfort, these electrical ...
