ETAP Arc Flash Analysis estimates the arc flash incident energy under a bolted three-phase short circuit fault and determines the flash protective boundary to live parts for shock protection. Design safer power systems by insuring compliance with OSHA, NFPA 70E, and IEEE 1584™ standards. Determine the suitable Personal Protective Equipment (PPE) rating requirements based on calculated incident energy and arc flash boundaries integrated with coordination time of protective devices. Arc Flash Analysis is conducted in conjunction with the ANSI/IEEE and IEC short circuit device duty calculations. |
