Fundamental electrical engineering concepts and theory
A quick post in connection with an email question: Live Tank - the circuit breaker the switching unit is located in an insulator bushing which is live...
Traditionally substations have used circuit breakers, current transformers (CT), voltage transformers (VT) and protection relays all wired together using...
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...
Delum, who had watched all in silence, his face empty of expression, now spoke in turn. ' "Lead us, Warleader, into glory."' Reading is something I do...
The International System of Units (abbreviated SI) is the world's most widely used system of units. The system consists of a set of units and prefixes...
This is the first of two posts on the resistance of conductors. In the next post I will look at the ac resistance, including skin effect and we deal with...
Depending where in the world you work, you are likely following one of two standards International Electrotechnical Commission (IEC) National...
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...
In three phase systems, the use of transformers with three windings (or legs) per side is common. These three windings are often connected in delta or...
