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...

Cable insulation is used to provide electrical separation between conductors of  a cable.  During the historical development of cables, numerous types...

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...

For unbalance conditions the calculation of fault currents is more complex. One method of dealing with this is symmetrical components. Using symmetrical...

When sizing cables, the heat generated  by losses within any sheath or armour need to be evaluated. When significant, it becomes a factor to be considered...

Capacitors have numerous applications in electrical and electronic applications.  This note examines the use of capacitors to store electrical energy....

Per unit fault calculations is a method whereby system impedances and quantities are normalised across different voltage levels to a common base.  By removing...

Motor starting and its associated problems are well-known to many people who have worked on large industrial processes. However, these things are, of course...

Carrying out a protection system discrimination study is critical to ensure the correct functioning of  the electrical system in the event of faults. ...

The calculation of current in a three phase system has been brought up on our site feedback and is a discussion I seem to get involved in every now and...
