Arc Flash Analysis
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.
The Arc Flash Analysis is conducted in conjunction with the ANSI/IEEE and IEC Short-Circuit Device Duty calculations.
Features
- Use .5 cycle or 1.5 to 4 cycle short circuit current
- Use system calculated or user-defined bolted fault current
- Automatically determine individual arcing current contributions
- Automatically determine the arcing fault clearing time
- Use system calculated or user-defined system grounding
- Automatic determination of hazard/risk categories for selecting PPE (based on NFPA 70E 2000/2004)
User-defined hazard/risk categories for selecting PPE - Quick incident energy calculator (bus arc flash page)
- Available plots for the calculated incident energy vs. time & arcing current in Star (device coordination)
- Flash protection, prohibited, restricted, & limited approach boundaries according to NFPA 70E
- Consider arcing current variation to determine the incident energy
- User-defined equipment gap between conductors/buses & X-factors
- Automatically determine bolted short circuit current for every faulted bus
Capabilities
- Different label templates available for each faulted equipment
- Analysis of cable bus arcs (IEEE 1584-2002)
- Create labels for buses or individual protective devices
- Determines the flash protection boundary for enclosed & open air configurations
- Automatically determine the worst-case scenario fault clearing time from the Star TCCs.
- Determine incident energy exposure at working distance & fault clearing time
- Create regulation arc flash hazard labels for every bus in the system
