Understanding Arc Flash Hazard Analysis

Learn the elements of an Arc Flash Risk Assessment

Arc flash hazard analysis is one of the major components of electrical systems design that requires a meticulous level of detail and accuracy as it defines the available fault current, calculated incident energy which results in arc flash labels, boundary conditions and PPE requirements for the electrical safety programs.

This webinar will address the information that needs to be gathered for system modeling to include, equipment details, duty cycles, single-line diagrams, overcurrent protection devices, transformer ratings with impedances etc. and how to analyze them. The topic will also touch on the importance and considerations for selective coordination to localize the faults to avoid nuisance tripping of the upstream breakers and how simple modifications to the breaker settings and the fuse ratings can be utilized to limit the arc flash potential.

Learning objectives:

  • Elements of an Arc Flash Risk Assessment
  • System modeling: “How far into the system do we study?”
  • Short-Circuit Current calculations & Equipment Duty studies
  • Coordination studies & Incident Energy Calculations
  • Formatting the study for non-engineers & Labeling requirements
