Fundamental electrical engineering concepts and theory
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...
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...
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
GE have put together a time-lapse video shown flight take-off and landings at some airports. An interesting view:
In an earlier note on the site [Photovoltaic (PV) - Electrical Calculations], the theory of solar (PV) cell calculations was introduced. In particular...
Motor starting and its associated problems are well-known to many people who have worked on large industrial processes. However, these things are, of course...
Per unit fault calculations is a method whereby system impedances and quantities are normalised across different voltage levels to a common base. By removing...
Various arguments exist around SF6 Gas Insulated (GIS) and Air Insulated (AIS) medium voltage switchgear. Recently we had to change a GIS design to AI...
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...
A recurring theme on our forums is cable sizing. Now many installations are unique and require special consideration. However, a lot of the time things...
