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...
Request to look at induction motor starting time have come up a few times on the site. Hopefully in this post, I give you guys some idea on how to calculate...
Often document control is dictated by project requirements, for example a particular organisation may have an existing numbering system. Existing company...
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...
Variable frequency drives are widely used to control the speed of ac motors. This note looks at the mechanisms which enable drive units to control the...
The image (reproduced from IEC 60909) shows a typical fault in an ac system. From the illustration it can seen that there is an initial dc component ...
Using software in our work is essential for most of us and we are becoming even more dependant on it's use. While software is a great asset, many times...
Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...
Capacitors have numerous applications in electrical and electronic applications. This note examines the use of capacitors to store electrical energy....
