High-Voltage Arc Flash Assessment and Applications, Part 1

  • Regulatory Requirements
  • Methodology
  • Calculation Method Comparisons
  • Conclusion
  • References
    • Arc flash has been identified by OSHA’s regulatory bodies as a serious hazard requiring prompt mitigation action. OSHA Article 1910.335 states: “to warn and protect employees from hazards which could cause injury due to electric shock, burns, or failure of electric equipment parts.” In Section 5(a)(1) of the 1970 Occupational Safety and Health Act,...

      • HV Transmission Line Protection and Clearing Time
      • Pole Construction and Gap Between Conductors
      • Case Study: Calculating HV and MV Arc Flash Incident Energy
      • Analysis
      • Conclusion
      • References
        • The three most important driving factors that directly affect arc-flash energy are the short-circuit current, the gap between conductors, and the duration of the arc. Incident energy increases with higher short-circuit currents. However, due to the operation of protective devices (PD), higher short-circuit currents can result in lower incident ener...
