DC Arc Flash Software

ETAP DC Arc Flash module calculates the incident energy for different types of DC applications including mission critical facilities, solar generation sites, substation battery banks and nuclear plants.

ETAP DC Arc Flash complies with NFPA 70E 2012 Annex D.8 which is dedicated to the direct current incident energy calculation. This module allows the engineer to compare DC arc flash incident energy values and determine the most conservative results.

AC Arc Flash is offered as a seperate module for the assessment of arc flash hazards and arc flash incident analysis.
