Arc Flash Analysis Step-by-Step Instructions for Vietnam - Carelabs Vietnam

An arc flash study for a Vietnamese facility follows the same core process regardless of industry:

1. Scope definition. Identify which panels, switchgear, and distribution points the study will cover.
2. On-site data collection. Field engineers record equipment ratings, protective device settings, and system configuration.
3. ETAP modelling. The collected data is built into a system model in ETAP software.
4. Incident energy calculation. Using the IEEE 1584 method, incident energy is calculated at every working point in the model.
5. PPE category and labelling. Each working point is assigned an arc flash boundary and PPE category, and labels are prepared for installation on equipment.
6. Reporting. A final report package — aligned with TCVN 7447 — documents every calculation, label, and recommendation.
