Fault current calculation software free

Fault current calculation software free electronic for dummies In this case the fault current was reduced from 31,378 amps to 26,566 amps, approximately 15.3%. Figure 8. Summary of calculations and comparison with other tools to calculate available fault current. Final Calibration. So we have walked through the calculation of available fault current for service-entrance equipment.


Issue: Transformer Available Fault Current Product Line LV Transformers Environment: Applies to LV Transformers by Square D/Schneider Electric Cause: Transformers are often connected to equipment that is rated for certain AIC, Average Interrupting Current, or Available Fault Current Resolution: Take the secondary full load current of the Transformer and divide it by the Transformer`s impedance. This is not necessary on Transformers below 15k VA, thus why UL does not require the impedance on the nameplate of Transformers below 15k VA. For example, a 75k VA Transformer with a 208Y/120 secondary and 5% impedance has a capacity of 208 amps on the secondary. The peak let through with an infinite source (worst case scenario) would have 208 / 0.05 = 4,160 amps of peak let through current (available fault current).

These new online software tools will progressively substitute Curve Direct and Direct Coordination.
