Intended to give help for the application of IEC 60909-0 for the calculation of short-circuit currents in 50 Hz or 60 Hz three-phase a.c. systems. It does not include additional requirements but does give support for the modelling of electrical equipment in the positive-sequence, the negative-sequence and the zero-sequence system and the practical execution of calculations in a low-voltage system, a medium-voltage system with asynchronous motors and a power-station unit with its auxiliary network feeding a large number of medium-voltage asynchronous motors and low-voltage motor groups.
