Fundamental electrical engineering concepts and theory
Problems on achieving maximum voltage drop within an installation come up often. Depending where you live, local regulations will have different limits...
If you have no idea how electrical circuits work, or what people mean then they talk about volts and amps, hopefully I can shed a bit light. I’m intending...
If you have a great idea or invent something the last thing you want is someone to steal the idea. One of the things you can do is protect the intellectual...
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...
Capacitors have numerous applications in electrical and electronic applications. This note examines the use of capacitors to store electrical energy....
This post is quick introduction and overview to different railway electrification voltages used in answer to a question sent in via email. While there...
Most installations involve some form of lightning protection system which is connected to an earth electrode. The function of the earth electrode is to...
Traditionally generation of electricity has involved rotating machines to produce alternating sinusoidal voltage and current (a.c. systems). With the development...
The other day I was talking to a colleague who is a building services consultant. Despite regularly specifying dry-type/cast resin transformers he was...
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 ...
