This workshop teaches electrical troubleshooting and is concerned with the calculation of fault currents in electrical power systems.  Short – circuit currents are associated with large amounts of very destructive energy and therefore calculation must be made to ensure that the short circuit rations of equipment are adequate to cater for these high currents.
