Fundamental electrical engineering concepts and theory
The calculation of current in a three phase system has been brought up on our site feedback and is a discussion I seem to get involved in every now and...
If you are working on a large plan, get the real coordinates [latitude, longitude] for two or more points and add them to the drawing. That way you can...
Gauss's Electrical law defines the relation between charge ("Positive" & "Negative") and electric field. The law was initially formulated by Carl Friedrich...
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...
The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.
Dielectrics (insulating materials for example) when subjected to a varying electric field, will have some energy loss. The varying electric field causes...
The other day I came across an article in Technology Review on the development of a smart transformer. A professor at North Carolina State University is...
Problems on achieving maximum voltage drop within an installation come up often. Depending where you live, local regulations will have different limits...
This post is quick introduction and overview to different railway electrification voltages used in answer to a question sent in via email. While there...
Over recent years the Lithium Ion battery has become popular in applications requiring high power densities with small weight and footprint. Today Lithium...
