Arc-Flash Analysis

What is arc-flash analysis?

For the protection of personnel working on a power system network, it is essential to determine the arc-flash risks for all specified potential arc-flash events. These can be reported in terms of incident thermal energy, allowing the necessary control measures to be put in place.

Arc-Flash Analysis in PowerFactory

The analysis in PowerFactory is carried out according to various international recognised standards and recommendations.  Calculations of incident energy and PPE recommendations are reported, and the tool includes an option for generating arc-flash labels.

• Arc-Flash calculation for AC systems in accordance with IEEE 1584-2002 and -2018, NFPA 70E-2021 and DGUV 203-077 and EPRI
• Arc-Flash calculation for DC systems in accordance with NFPA 70E-2021 and DGUV 203-077
• Incident Energy, Flash-Protection Boundary and PPE Category on the single line diagram
• Automated preparation of Arc-Flash labels
• Automatic protection-based fault clearing time determination¹
