The calculation of short-circuit currents in d.c. auxiliary installations, e.g., in power plants and substations is dealt with in IEC 61660-1. Contrary to the approach for the calculation of short-circuit currents in a.c. three-phase systems, the determination of the exact time course of the short-circuit current is needed besides the calculation of defined parameters.
