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 60909-0:2016 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.

A short-circuit current rating (SCCR)1 is the maximum current a device or system can safely withstand for a specified time (such as 0.05 seconds), or until a specified fuse or circuit breaker opens and clears the circuit.

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. Maximum short-circuit currents determine equipment ratings, while minimum currents dictate protective device settings.

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.

ETAP Short Circuit Analysis complies with IEC 61363 standard, required for electrical installations on ships or mobile and fixed offshore units. It includes pre-fault loading conditions using load-flow analysis to calculate short circuit currents precisely along with detailed device duty reports and OLV alerts.

Fault current calculations are based on Ohm's Law in which the current (I) equals the voltage (V) divided by the resistance (R). The formula is I = V/R.

IEC 60909 is being used to analyse the short circuit performance of the typical plant. In IEC 60909 standard, the initial symmetrical current is obtained by using the nominal voltage, voltage factor (C) and equivalent impedance at the fault location.
