Fundamental electrical engineering concepts and theory
IEC 62305 'Protection against lightning' requires a risk assessment be carried out to determine the characteristics of any lightning protection system...
If you are wondering what happened to our cable notes, the short answer is that we have moved them to myCableEngineering.com. The "Knowledge Base" at...
Years ago I was told that you should always try to write the best report you can. Many years later I still think on this as one of the better pieces of...
Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading...
The image (reproduced from IEC 60909) shows a typical fault in an ac system. From the illustration it can seen that there is an initial dc component ...
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...
IEC 60228 is the International Electrotechnical Commission's international standard on conductors of insulated cables. Among other things, it defines a...
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
In three phase systems, the use of transformers with three windings (or legs) per side is common. These three windings are often connected in delta or...
This post is quick introduction and overview to different railway electrification voltages used in answer to a question sent in via email. While there...
