Problems on achieving maximum voltage drop within an installation come up often. Depending where you live, local regulations will have different limits...

In the previous note we looked at the approach taken by the standard to the sizing of cables and illustrated this with an example.  We then looked at one...

Carrying out a protection system discrimination study is critical to ensure the correct functioning of  the electrical system in the event of faults. ...

If you are working on a large plan, get the real coordinates [latitude, longitude] for two or more points and add them to the drawing. That way you can...

Photovoltaic (PV) cells (sometimes called solar cells) convert solar energy into electrical energy.  Every year more and more PV systems are installed...

Years ago I was told that you should always try to write the best report you can.  Many years later I still think on this as one of the better pieces of...

I have been thinking recently that there appears to be less professional integrity around than when I first started my career in electrical engineering...

It's been a busy few months on different projects or busy couple of decades depending on how I look at it. I can say that on the odd (frequent) occasion...

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

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...
