Both DC and AC Arc Flash Analysis are important hazard assessment components of Power Systems Analysis software. ETAP’s DC Arc Flash Analysis module calculates the DC incident energy for different types of applications including high-impact facilities, renewable energy sites, as well as battery banks for substations and nuclear generating plants.

 

The ETAP DC Arc Flash module complies with NFPA 70E 2012 Annex D.8. This new edition to the NFPA 70E standard focuses on direct current incident energy calculations. This enables engineer to determine DC arc flash incident energy values and calculate conservative results.
