The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.
When looking at the design of a lighting scheme it is useful to have an understanding on the nature of light itself and some of the basic theory associated...
Maxwell's Equations are a set of fundamental relationships, which govern how electric and magnetic fields interact. The equations explain how these fields...
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...
In a previous article I looked at the dc resistance of conductors and in this article we turn our attention to ac resistance. If you have not read the...
Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...
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...
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...
Photovoltaic (PV) cells (sometimes called solar cells) convert solar energy into electrical energy. Every year more and more PV systems are installed...
