Also included are the summary reports for all the faulted buses in the system which, include the flash protection boundaries and the calculated hazard/risk level assessment. The arc flash reports include the arcing current contributions passing through each protective device, the calculated fault clearing time and the hazard analysis results. Also included are the typical boundaries and equipment gaps provided for by the IEEE 1584 and NFPA 70E. In addition, the arc flash analysis will determine the system grounding configuration and other information required to determine the most adequate and conservative hazard analysis results. Calculations of the individual arcing current contributions and arc fault clearing time of all the protective devices involved in the arc fault are provided. The arc flash values automatically determine the bolted short circuit current using the existing single line diagrams short circuit analysis. National Fire Protection Agency (NFPA) 70E-2015.The incident energy and flash protection boundaries are determined based on the following two available standards for arc flash analysis: Arc Flash/Fault Analysis investigate a worker’s potential exposure to arc flash energy, which may be required for the purpose of injury prevention and determination of appropriate levels of personal equipment protection (PPE) ratings.
