Revidiran
Applicable to the calculation of short-circuit currents:
- in low-voltage three-phase a.c. systems
- in high-voltage three-phase a.c. 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.
