Power systems theory - generation, transmissions and distribution
Alternating current (a.c.) is the backbone of modern electrical power distribution. In this article I’ll be pulling some of the more important concepts...
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...
If you at all familiar with programs like office and outlook, then adding and editing posts is pretty straightforward and intuitive. However, there are...
Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...
Coils of wire on the rotor carry a d.c. current which generates a magnetic field. A stator magnetic field is created using either permanent magnets or...
Cable insulation is used to provide electrical separation between conductors of a cable. During the historical development of cables, numerous types...
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...
Per unit fault calculations is a method whereby system impedances and quantities are normalised across different voltage levels to a common base. By removing...
If you are wondering what happened to our cable notes, the short answer is that we have moved them to myCableEngineering.com. The "Knowledge Base" at...
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...
