Fundamental electrical engineering concepts and theory
If you have no idea how electrical circuits work, or what people mean then they talk about volts and amps, hopefully I can shed a bit light. I’m intending...
The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.
Problems on achieving maximum voltage drop within an installation come up often. Depending where you live, local regulations will have different limits...
A recurring theme on our forums is cable sizing. Now many installations are unique and require special consideration. However, a lot of the time things...
GE's latest thinking on product manufacturing is he Shingijutsu philosophy or Lean production system. They have started applying this at the Louisville...
The fundamental component of any analogue computer is the operational amplifier, or op amp. An operational amplifier (often called an op-amp,) is a high...
Per unit fault calculations is a method whereby system impedances and quantities are normalised across different voltage levels to a common base. By removing...
HTML supports a variety of entity symbols which can be entered using either numbers or an entity name. The number or name is preceded by the ‘&’ sign...
Everything physical in electrical engineering from insulations to conductors revolves around materials. Here we are listing common materials along with...
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...
