Power systems analysis, standards interpretation, and asset intelligence — written by the engineers doing the work.
Arc flash assessments are mandated under AS/NZS 2067, but the standard leaves considerable room for interpretation on incident energy thresholds, boundary calculations, and the conditions under which engineering controls supersede PPE selection. This article addresses the decision points that catch asset owners out in the field — and where ETAP's IEEE 1584-2018 engine changes the calculus compared to earlier calculation methods.
