Power systems theory - generation, transmissions and distribution
Maxwell's Equations are a set of fundamental relationships, which govern how electric and magnetic fields interact. The equations explain how these fields...
A lot of our members work in countries where PPE (personal protective equipment) is regulated or they work for companies/organizations which take employee...
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...
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...
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 ...

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...
We have had the Wiki with us for a long time now, but at last I have decided to say bye bye – more details on why below.
This is the second post in a series of two on periodic electrical inspections. In the first post, I discussed how often inspections should be carried out...
Many questions sent in to the site are in connection with motor starting and in particular star-delta. For all but the simplest application, there is...
