Fundamental electrical engineering concepts and theory
While there are a vast array of cable insulation materials, these are often divided into two general types; Thermoplastic or Thermosetting. For example...
I have been thinking recently that there appears to be less professional integrity around than when I first started my career in electrical engineering...
Many questions sent in to the site are in connection with motor starting and in particular star-delta. For all but the simplest application, there is...
A fundamental concept behind the operation of alternating current systems is that voltage and current waveforms will be sinusoidal – a Sine Wave. This...
The robot folding towels post below was interesting enough at the time to post a link. Recently I’ve come across a couple of other interesting videos...
When selecting a generator, there are inherent limits on the active and reactive power which can be delivered. Generators are normally sized for a certain...
Over the past year or so I've been involved in on going discussions related to referring fault levels from the secondary of a transformer to the primary...
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...
Most installations involve some form of lightning protection system which is connected to an earth electrode. The function of the earth electrode is to...
IEC 60228 is the International Electrotechnical Commission's international standard on conductors of insulated cables. Among other things, it defines a...
