When looking at the design of a lighting scheme it is useful to have an understanding on the nature of light itself and some of the basic theory associated...
It wasn't so long ago I was telling someone that I don't use rules of thumb as most things are easily calculated anyhow. As it turns out I last week...
For unbalance conditions the calculation of fault currents is more complex. One method of dealing with this is symmetrical components. Using symmetrical...
