ARC-FLASH STUDY Steps to be followed (perform) for Arc-Flash Analysis By, Santhakumar Sampath
Santhakumar S 1 | P a g e INTRODUCTION TO THIS ARTICLE: ✓ This article covers the Arc-Flash Study/Analysis process (configuration, calculation - Arc Flash Boundary, Incident Energy, and working distance) in accordance with IEEE-1584 . This article does not include the introduction of Arc-Flash nor the recommendation of PPE (Personnel Protective Equipment) to prevent from an Arc-Flash event. ✓ The primary objective of the Arc-Flash study is to find Incident Energy for that we need “i” and “t” , where ➢ “i” is the fault current determined from Short-Circuit study ➢ “t” is fault clearing time determined from the Relay coordination study So Short Circuit and Relay Coordination study is mandatory before doing an Arc-Flash study. ✓ Arc Flash study outcomes are ➢ Arc Flash Boundary ➢ Incident Energy ➢ Working Distance From this outcome, we can recommend what type and which level of PPE is required based on NFPA-70E 2021 standard which will be covered in my next article.
