Fundamental electrical engineering concepts and theory
Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...
In three phase systems, the use of transformers with three windings (or legs) per side is common. These three windings are often connected in delta or...
The European Union is implementing a voluntary code of practice for participants with the aim of improving the overall efficiency of data centres. As part...
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...
Tapping your forearm or hand with a finger could soon be the way you interact with gadgets. A new technology created by Microsoft and Carnegie Mellon ...
I've recently come across this question a couple times browsing the internet. Decided to give a quick answer here. A rectifier transformer is a transformer...
Traditionally generation of electricity has involved rotating machines to produce alternating sinusoidal voltage and current (a.c. systems). With the development...
At the beginning of the year China put the world's first 1,000 kV UHV transmission system into operation. Transmitting power at over a million volts is...
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...
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...
