標(biāo)準(zhǔn)簡介
Establishes, in the calculation of short-circuits, a general, practicable and concise procedure leading to conservative results with sufficient accuracy. Applies to the calculation of short-circuits in: low-voltage three-phase a.c. systems; high-voltage three-phase a.c. systems with nominal voltages up to 380 kV operating at nominal frequency (50 Hz or 60 Hz). Coverage includes definitions, calculation assumptions, and influence of motors.
