Short-circuit currents in three-phase a.c. systems - Calculation of currents Ingestion-build-251241 BS EN 4191 gives you1 Scope This part of IEC 60909 is applicable to the calculation of short circuit currents in low voltage three phase AC systems, and in high voltage three phase AC systems, operating at a nominal frequency of 50 Hz or 60 Hz. Systems at highest voltages of 550 kV and above with long transmission lines need special consideration. This part of IEC 60909 establishes a general, practicable and concise procedure leading to results which are generally of
