ETAP Short Circuit Analysis complies with IEC 60909 standard, which classifies short-circuit currents ing to their magnitudes (maximum and minimum) and fault distances from generators.

ANSI is a design-based standard, while IEC tends to be a performance-based standard. a. ANSI standards can specify sheet metal thickness, paint color, barriers and other features to ensure consistency of equipment from various manufacturers.

IEC methodology is CURRENT based, while the ANSI / IEEE methodology is IMPEDANCE based. 2. DC Decay Component for Parallel or Meshed paths. Both IEC and ANSI / IEEE recognize that the transient solution to the short-circuit current calculation must be uniquely accomplished when parallel or meshed paths are involved.

IEC 60909-0:2016 is applicable to the calculation of short-circuit currents in low-voltage three-phase AC systems, and in high-voltage three-phase AC systems, operating at a nominal frequency of 50 Hz or 60 Hz.

IEC 60909 short-circuit calculation The introduction of the voltage correction factor c basically increases the voltage magnitude of the voltage source applied to the passive network N2 by 10%. This makes the fault current at least 10% higher and sometimes leads to more conservative (pessimistic) results.

IEC 60909 short-circuit calculation is similar to the short-circuit current calculation ANSI / IEEE 141. The most important differences are the use of a voltage correction factors (c=1.1 for high-voltage networks) and impedance correction factors.

ANSI 30 cycle calculation is used for relay coordination while IEC minimum fault is used for relay coordination. This study presents the basic assumptions of both standards and an example of calculation on MV Industrial network.
