GB/T 15544-1995 Calculation of short-circuit current in three-phase AC systems

This standard specifies the calculation of short-circuit current in three-phase AC systems using the equivalent voltage source method, and proposes the method and recommended value of the correction system used in the calculation. This standard is applicable to the calculation of short-circuit current in three-phase AC systems with a nominal voltage of 380V~220kV and a frequency of 50Hz. This standard is not applicable to the calculation of short-circuit of artificial short circuits and electrical equipment for aircraft and ships under controlled conditions (short-circuit test stations). This standard is mainly used for import and export equipment and foreign engineering bidding, and is gradually promoted and adopted in domestic engineering calculations.
