Short circuit Calculation

Many papers are there on the web, also in CR4. You can find by using the search window on the right.

Here is one paper : ect158.pdf

Reading a paper from the web is certainly one of the cheapest ways to produce a short circuit calculation but it is not the easiest. This may not even produce an accurate calculation because the reader has to understand and apply the correct information from any paper. (The Schneider Electric application note you cite though is an excellent paper.) The easiest method is to hire a qualified electrical engineer and have them do the calculation. By hiring an electrical engineer you'll even get the pedigree of the EE schooling to support the calculation.

Just my two cents and at no charge.

determine/establish your system VA,voltage,Current and impeadance..the common method is using your tansformer ratings..then transform every connected load presented in their corresponding impeadances..and use a 3 phase fault calculation for this much easier and gives out the highest value of short circuit current..
