Fundamental electrical engineering concepts and theory
Most installations involve some form of lightning protection system which is connected to an earth electrode. The function of the earth electrode is to...
Just added a page to the tools, which will allow you to calculate the synchronous speed, slip and rated torque for an induction motor. Not a particularly...
Two driverless and solar power vans have departed from Italy on their way to China via the silk road. During the 13,000 kM trip the vans will drive themselves...
I think this post is going to be helpful to several of our readers. While the IEC low voltage circuit breaker Standard [IEC 60947-2, Low voltage switchgear...
IEC 60947 is the circuit breaker standard and covers the marking of breakers in detail. Any manufacturer following this standard should comply with the...
The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.
Straight forward list of some common motor faults. If I have missed any other common faults, please take a bit of time to add them in as a comment below...
Often document control is dictated by project requirements, for example a particular organisation may have an existing numbering system. Existing company...
The other day I came across an article in Technology Review on the development of a smart transformer. A professor at North Carolina State University is...
Photovoltaic (PV) systems are typically more efficient when connected in parallel with a main power gird. During periods when the PV system generates energy...
