Carrying out a protection system discrimination study is critical to ensure the correct functioning of the electrical system in the event of faults. The IEC defines discrimination as:
A single phase system is perhaps the most common type of system most people are familiar with. This is what people have in their homes and what appliances...
I was having a conversation the other day about voltage levels. While everyone was in agreement that low voltage was 1000 V and less, there was more confusion...
Electrical notes are a collaborative collection of electrical engineering information and educational material. Any registered user can add content. ...
Per unit fault calculations is a method whereby system impedances and quantities are normalised across different voltage levels to a common base. By removing...
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...
Alternating current (a.c.) is the backbone of modern electrical power distribution. In this article I’ll be pulling some of the more important concepts...
GE have put together a time-lapse video shown flight take-off and landings at some airports. An interesting view:
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...
MIT OpenCourseWare, makes the materials used in teaching all MIT subjects available on the Web, free of charge, to any user in the world.
Using software in our work is essential for most of us and we are becoming even more dependant on it's use. While software is a great asset, many times...
