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