ArcFault™ - Arcing Fault Hazard Evaluation

ArcFault - High Voltage Arc Flash

High Voltage Arc Flash - NESC / OSHA

Arcing Fault Hazard Evaluation for up to 800 kV
ETAP ArcFault™ analysis software is used for performing Arc Flash Analysis on
electric transmission and distribution utilities and renewable power systems operating
at 1000 volts and above.
HVAF
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.
