ArcFault - High Voltage Arc Flash

High Voltage Arc Flash

Arcing Fault Hazard Evaluation for medium and high voltage systems

ETAP ArcFault™ analysis software is used for performing Arc Flash Analysis on electric transmission and distribution utilities, industrial and renewable power systems operating at 1 kV and above.

The ArcFault analysis program allows the simulation of different types of faults in 3-phase and 1-phase systems without the need of externally calculating short circuit currents and protective device operation time. The program automatically determines the working distance and minimum approach distance based on the system voltage, transient overvoltage conditions, and altitude.

ArcFault contains customizable calculation methods and equations allowing the user to account for future research on arc fault physical behavior.

ArcFault is fully integrated with Star™ protective device coordination module utilizing time-current characteristic (TCC) curves and short circuit calculations for arcing fault hazard evaluation.
