Power systems theory - generation, transmissions and distribution
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
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...
If you have a great idea or invent something the last thing you want is someone to steal the idea. One of the things you can do is protect the intellectual...
IEC 60947 is the circuit breaker standard and covers the marking of breakers in detail. Any manufacturer following this standard should comply with the...

We have had the Wiki with us for a long time now, but at last I have decided to say bye bye – more details on why below.
Laplace transforms and their inverse are a mathematical technique which allows us to solve differential equations, by primarily using algebraic methods...
Our cable sizing tool is one of the more popular tools on the site. The tool enables cables to be sized in compliance with BS 7671 (the IEE Wiring Regulations...
Current transformers (CTs) are used to convert high level currents to a smaller more reasonable level for use as inputs to protection relays and metering...
Most installations involve some form of lightning protection system which is connected to an earth electrode. The function of the earth electrode is to...
