These lifts were first built in 1884 by J. E. Hall and called a paternoster ("Our Father", the first two words of the Lord's Prayer in Latin) due to its...
The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.
Electrical engineering has a multitude of laws and theorems. It is fair to say the Ohm's Law is one of the more widely known; it not the most known. Developed...
For unbalance conditions the calculation of fault currents is more complex. One method of dealing with this is symmetrical components. Using symmetrical...
I have been thinking recently that there appears to be less professional integrity around than when I first started my career in electrical engineering...
