I've been considering a blog on the 110 or 230 Volt issue for a while.  While browsing the Internet I came across a great summary by Borat over at  engineering...

Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading...

Dielectrics (insulating materials for example) when subjected to a varying electric field, will have some energy loss.   The varying electric field causes...

The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.

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...

Capacitors have numerous applications in electrical and electronic applications.  This note examines the use of capacitors to store electrical energy....

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

Two driverless and solar power vans have departed from Italy on their way to China via the silk road. During the 13,000 kM trip the vans will drive themselves...

Multimeters are undoubtedly the most common item of electrical test equipment in use.  Often it is the first piece of equipment people will turn to when...

Following on from my post on railway electrification voltages, I thought an introduction to traction substations would be a good idea. Traction substations...
