Short-Circuit study in Desalination Plant (Morocco)

The short-circuit study of the electrical network in a Desalination Plant has been carried out. The three-phase, single-phase (L-G) and two-phase (L-L & L-L-G) faults have been calculated in accordance with international standards. With this study, maximum short-circuit values are obtained that allow to select the adequate protections for the system and minimum values of short-circuit current needed to develop selectivity studies.
