ArcFault™ - Arc Fault Hazard Evaluation


Arcing Fault Hazard Evaluation - NESC

Simulate PD Operation    Improve Safety    Simplify Compliance
ETAP ArcFault™ analysis software calculates the incident energy for electrical utility transmission and distribution systems.
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.
