DC Arc Flash Analysis

Design Calculate Evaluate

ETAP DC Arc Flash software calculates the incident energy for different types of direct current applications, including mission critical facilities, electrochemical plants, substation battery banks, photovoltaic plants, nuclear plants, and transportation systems.

ETAP DC Arc Flash complies with NFPA 70E 2018 Annex D.5.1 to D.5.3. This module allows the engineer to compare DC arc flash incident energy values and determine the most conservative results using a network-based solution and a powerful DC arc flash calculator.
