Power systems theory - generation, transmissions and distribution
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...
A battery consists of one or more cells, each of which use stored chemical energy to produce electrical energy, There are many types of cells and these...
Working in the vicinity of electrical equipment poses an hazard. In addition to electric shock hazard, fault currents passing through air causes Arc Flash...

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...
If you want to check a circuit is dead (not live), you should always use the three point method. First check a known live circuit, then check the dead...
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...
Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...
This is the first of two posts on the resistance of conductors. In the next post I will look at the ac resistance, including skin effect and we deal with...
A fundamental concept behind the operation of alternating current systems is that voltage and current waveforms will be sinusoidal – a Sine Wave. This...
