The other day I came across an article in Technology Review on the development of a smart transformer. A professor at North Carolina State University is...

This morning I was explaining how differential protection works to a junior engineer. To give him something to read I opened up the NPAG (Network Protection...

I was having a conversation the other day about voltage levels.  While everyone was in agreement that low voltage was 1000 V and less, there was more confusion...

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

GE have put together a time-lapse video shown flight take-off and landings at some airports. An interesting view:

The (relatively new) switchgear and control gear standard, IEC 61439 'Low-voltage switchgear and controlgear assemblies' has three methods which can be...

I think this post is going to be helpful to several of our readers. While the IEC low voltage circuit breaker Standard [IEC 60947-2, Low voltage switchgear...

IEEE TV has a part series of videos on wind power and it's implication. For a really good overview to the technologies and issues around wind power, these...

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

If you want to check a circuit is dead (not live), you should always use the three point method. First check a known live circuit, then check the dead...
