Fundamental electrical engineering concepts and theory
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...
If your are ever called out to troubleshoot something on your electrical system, one of the first things consider is the supply voltage. You want to ensure...
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...
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
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...
Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading...
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...
