Exposure to time varying magnetic fields, from power frequencies to the gigahertz range can have harmful consequences. A lot of research has been conducted...
Per unit fault calculations is a method whereby system impedances and quantities are normalised across different voltage levels to a common base. By removing...
When sizing cables nearly, everyone uses some form of software. This ranges from homespun spreadsheets to complex network analyses software. Each has its...
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.
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...
In three phase systems, the use of transformers with three windings (or legs) per side is common. These three windings are often connected in delta or...
Traditionally substations have used circuit breakers, current transformers (CT), voltage transformers (VT) and protection relays all wired together using...
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
Everything physical in electrical engineering from insulations to conductors revolves around materials. Here we are listing common materials along with...
GE have put together a time-lapse video shown flight take-off and landings at some airports. An interesting view:
