Fundamental electrical engineering concepts and theory
This is the second post in a series of two on periodic electrical inspections. In the first post, I discussed how often inspections should be carried out...
It's been a busy few months on different projects or busy couple of decades depending on how I look at it. I can say that on the odd (frequent) occasion...
This article gives an introduction to IEEE 485 method for the selection and calculation of battery capacity.
Traditionally generation of electricity has involved rotating machines to produce alternating sinusoidal voltage and current (a.c. systems). With the development...
The (relatively new) switchgear and control gear standard, IEC 61439 'Low-voltage switchgear and controlgear assemblies' has three methods which can be...
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...
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...
We have a sister note to this (Robots - Interesting Video), in which I have posted some videos of interesting robots developed by commercial corporations...
Battery powered cars are a hot topic and widely debated. The pros, cons, issues and time frames can be talked about endlessly. An article by the Telegraph...
Many questions sent in to the site are in connection with motor starting and in particular star-delta. For all but the simplest application, there is...
