Fundamental electrical engineering concepts and theory
Famed English chemist and physicist Michael Faraday was born on September 22, 1791, in Newington Butts, a suburb of Surrey just south of the London Bridge...
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...
It wasn't so long ago I was telling someone that I don't use rules of thumb as most things are easily calculated anyhow. As it turns out I last week...
A frequent problem in fault calculations is the obtaining of equipment parameters. While it is always preferable to use the actual parameters of the equipment...
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...
I think this post is going to be helpful to several of our readers. While the IEC low voltage circuit breaker Standard [IEC 60947-2, Low voltage switchgear...
I was having a conversation the other day about voltage levels. While everyone was in agreement that low voltage was 1000 V and less, there was more confusion...
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...
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...
If you want to check a circuit is dead (not live), you should always use the three point method. First check a known live circuit, then check the dead...
