Fundamental electrical engineering concepts and theory
Ever wondered what kind of power an aircraft uses when parked at the airport stand. Normally the aircraft generates it own power, but when parked with...
Various techniques exist to enable the correct selection of batteries for UPS applications. The procedure described below is one of the more common. ...
The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.
While not as popular as it once was, frame leakage protection does still have some use in some circumstances. In essence frame leakage is an earth fault...
Alternating current (a.c.) is the backbone of modern electrical power distribution. In this article I’ll be pulling some of the more important concepts...
Just added a page to the tools, which will allow you to calculate the synchronous speed, slip and rated torque for an induction motor. Not a particularly...
Straight forward list of some common motor faults. If I have missed any other common faults, please take a bit of time to add them in as a comment below...
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...
A fundamental concept behind the operation of alternating current systems is that voltage and current waveforms will be sinusoidal – a Sine Wave. This...
