The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.

I've been considering a blog on the 110 or 230 Volt issue for a while.  While browsing the Internet I came across a great summary by Borat over at  engineering...

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...

IEEE TV has a part series of videos on wind power and it's implication. For a really good overview to the technologies and issues around wind power, these...

Power factor is the ratio between the real power (P in kW) and apparent power (S in kVA) drawn by an electrical load. The reactive power (Q in kVAr)...

I have been thinking recently that there appears to be less professional integrity around than when I first started my career in electrical engineering...

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...

I received this question by email a few weeks. First thoughts was that it is a product of the mathematics of rotating a straight conductor in a magnetic...

Problems on achieving maximum voltage drop within an installation come up often. Depending where you live, local regulations will have different limits...

Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...
