Fundamental electrical engineering concepts and theory
I was digging in my bookshelf and came across the 80th Anniversary Association of Mine Resident Engineers, Papers and Discussions Commemorative Edition...
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...
This morning I was explaining how differential protection works to a junior engineer. To give him something to read I opened up the NPAG (Network Protection...
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...
Various arguments exist around SF6 Gas Insulated (GIS) and Air Insulated (AIS) medium voltage switchgear. Recently we had to change a GIS design to AI...
When looking at the design of a lighting scheme it is useful to have an understanding on the nature of light itself and some of the basic theory associated...
Earthing of electrical systems is essential for the correct functioning and the protecting of life and equipment in the event of faults. The earth electrode...
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...
A single phase system is perhaps the most common type of system most people are familiar with. This is what people have in their homes and what appliances...
The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.
