The European Union is implementing a voluntary code of practice for participants with the aim of improving the overall efficiency of data centres. As part...
Variable frequency drives are widely used to control the speed of ac motors. This note looks at the mechanisms which enable drive units to control the...
This post is quick introduction and overview to different railway electrification voltages used in answer to a question sent in via email. While there...
Our question and answer system while letting you do exactly what it says, is much more. It is a dynamic user driven system, where our users not only ask...
Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...
The new standard IEC 61439 replaces the old 60439. Compared to the old standard, the new 61439 is a more clearly defined and takes into account the assembly...
One of the fundamental requirements of an alternating current distribution systems it to have the ability to change the magnitude of voltages. It is more...
I was digging in my bookshelf and came across the 80th Anniversary Association of Mine Resident Engineers, Papers and Discussions Commemorative Edition...
Following on from my post on railway electrification voltages, I thought an introduction to traction substations would be a good idea. Traction substations...
IEEE TV has a part series of videos on wind power and it's implication. For a really good overview to the technologies and issues around wind power, these...
