Fundamental electrical engineering concepts and theory
For unbalance conditions the calculation of fault currents is more complex. One method of dealing with this is symmetrical components. Using symmetrical...
Laplace transforms and their inverse are a mathematical technique which allows us to solve differential equations, by primarily using algebraic methods...
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
Cable insulation is used to provide electrical separation between conductors of a cable. During the historical development of cables, numerous types...
The new standard IEC 61439 replaces the old 60439. Compared to the old standard, the new 61439 is a more clearly defined and takes into account the assembly...
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...
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...
Often document control is dictated by project requirements, for example a particular organisation may have an existing numbering system. Existing company...
