Years ago I was told that you should always try to write the best report you can. Many years later I still think on this as one of the better pieces of advice. Not only does this apply ... read more..
Often us engineers get so bogged down in equations, using software, producing drawings and writing specifications that this becomes the sole focus. Good engineering design needs to go b... read more..
Resistors are electronic components that oppose the flow of current. Manufactured in various types and ranges they have a wide application to electronics...
One of the fundamental requirements of an alternating current distribution systems it to have the ability to change the magnitude of voltages. It is more...
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...
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
At the beginning of the year China put the world's first 1,000 kV UHV transmission system into operation. Transmitting power at over a million volts is...
Sometimes it’s useful to be able to quickly lookup a piece of technical information. This note is a collection of information related to motors, and in...
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.
When current flows within a wire, a magnetic field is created. The potion of this magnetic field perpendicular to the wire is called the magnetic flux...
Traditionally substations have used circuit breakers, current transformers (CT), voltage transformers (VT) and protection relays all wired together using...
The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.
