Fundamental electrical engineering concepts and theory
A frequent problem in fault calculations is the obtaining of equipment parameters. While it is always preferable to use the actual parameters of the equipment...
Control theory looks at how systems work and are controlled from a mathematical view. This note gives a brief introduction to some of the concepts – more...
Maxwell's Equations are a set of fundamental relationships, which govern how electric and magnetic fields interact. The equations explain how these fields...
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...
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...
Cable insulation is used to provide electrical separation between conductors of a cable. During the historical development of cables, numerous types...
Collection of links to various places with useful motor information. I’ll try and return to the page every now and again to update it with any motor notes...
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 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...
Estimating maximum demand is a topic frequently discussed. Working out how much power to allow for a building can be very subjective . Allowing too much...
