60909-0 O IEC:2001 -9- INTERNATIONAL ELECTROTECHNICAL COMMISSION FDIS SHORT-CIRCUIT CURRENTS IN THREE-PHASE AC SYSTEMS - Part O: Calculation of currents Report on voting FOREWORD 73/119/FDIS I) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The calculation method, used in the IEC Standard 60909 determines the short-circuit currents at the location F using equivalent voltage source: cU n / 3 . This source is defined as the voltage of an ideal source applied at the short-circuit location in the positive sequence system, whereas all other sources are ignored. All network components are replaced by their internal impedances (see Fig.1.).

The calculation of short circuit (SC) current has to be accurate because of their importance in power protection system’s design and to determine the capacity of the protective devices.

Short circuit impedance calculation techniques based on IEC 60909 with correction factors for synchronous generators, power supply units, and transformers. Determining the current paths whether ‘non-meshed’ or ‘meshed’ and the proximity of the fault, ‘far from’ or ‘near’ generators are prerequisites in the calculation of short circuit currents in IEC 60909.

    Short-circuit Current Calculation Application for A.C 3 Phase on Marine and Mobile Short-circuit Calculation Program The short circuit current calculation of IEC 61363 standards is intended for installations of three-phase ac system that operates at a frequency of 50 Hz or 60 Hz in a ships or offshore installations. The system has one or more levels which are different in The calculation method, used in the IEC Standard 60909 determines the short-circuit currents at the location F using equivalent voltage source: cU n / 3 . This source is defined as the voltage of an ideal source applied at the short-circuit location in the positive sequence system, whereas all other sources are ignored. All network components are replaced by their internal impedances (see Fig.1.).
