Short circuit current amplitude estimation using virtual instrumentation

Transient Signal Analysis is not easy when request a real-time procedure. A numerical method based on finite differences is presented in the paper. In this case, for estimation of a parameter, sufficient data must be available about the evolution of the signal. To prove the proper functioning of the method, a numerical simulation was made. A particular case, technically applicable, is related to the short circuit current estimation. Using the extension acquisition board, a full implementation can be done.
