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.

For unbalance conditions the calculation of fault currents is more complex. One method of dealing with this is symmetrical components. Using symmetrical...

Capacitors are widely used in electrical engineering for functions such as energy storage, power factor correction, voltage compensation and many others...

One of the fundamental requirements of an alternating current distribution systems it to have the ability to change the magnitude of voltages.  It is more...

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...

In an earlier note on the site [Photovoltaic (PV) - Electrical Calculations], the theory of solar (PV) cell calculations was introduced.  In particular...

Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...

The calculation of current in a three phase system has been brought up on our site feedback and is a discussion I seem to get involved in every now and...
