Arc Flash, Hazard Analysis


The nature of explosive equipment failures, and the rate of serious burn injuries in the electrical industry has been studied for many years. Detailed investigation into the arc flash phenomena by many researchers has led the NFPA to adopt arc flash guidelines in NFPA-70E (2000) for work on or near energized electrical equipment. The 2002 National Electric Code also adopted Arc Flash Hazard labeling requirements. In September of 2002, IEEE-1584 “IEEE Guide for Performing Arc Flash Hazard Calculations” was released, providing the detailed equations for determining arc flash energies. Proposed NFPA-70E (2003) due for adoption in May 2003 enhances the original 70E guidelines and adopts IEEE-1584 as the basis for determining arc flash energies. Arc-flash hazard studies require knowledge of both the electrical power system in a facility, and the systems electrical protection. Arc flash studies can be considered a continuation of the short circuit and coordination aspects of a power system, since the results for each are required to assess flash hazards. The effort required to perform an arc hazard assessment is greatly reduced the closer the integration between the short circuit, protective device coordination, and the arc-flash.
