The International System of Units (abbreviated SI) is the world's most widely used system of units. The system consists of a set of units and prefixes...
If you have no idea how electrical circuits work, or what people mean then they talk about volts and amps, hopefully I can shed a bit light. I’m intending...
Problems on achieving maximum voltage drop within an installation come up often. Depending where you live, local regulations will have different limits...
The other day I was talking to a colleague who is a building services consultant. Despite regularly specifying dry-type/cast resin transformers he was...
For unbalance conditions the calculation of fault currents is more complex. One method of dealing with this is symmetrical components. Using symmetrical...
We have had the Wiki with us for a long time now, but at last I have decided to say bye bye – more details on why below.
When thinking about watts (W) or kilowatt (kW = 1000 W) it can be useful too keep in mind the fundamental ideas behind the unit. Watt is not a pure electrical...
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...
