Web1 jul. 2012 · Fault Calculation - Symmetrical Components; IEC 60909 - Short-circuit currents in three-phase a.c. systems. Often when performing short circuit calculations, it is necessary to carry these out against a reference standard. By using a reference standard, calculations are consistent, can be justified and are provided with an audit trail. Web1 jul. 2008 · The IEC 60909 Standard is applicable for the calculation of short-circuit currents in 50 or 60 Hz three-phase ac systems. The equivalent voltage source method is adopted, permitting calculation of fault currents using only the nominal voltage of the system and rated values of the equipment. Several simplifications are inherent in the ...
