AFA V4.1   AFA V5.0  iAFA V1.0  DCAFA V2.0 

Arc-Flash-Analytic v 5.0 software tool has been developed based on IEEE 1584 Guide for Performing Arc-Flash Hazard Calculations as an easy to use and comprehensive instrument for calculating arc incident energy and arc flash boundary, for determining limited, restricted, prohibited approach boundaries and hazard risk category required by NEC / CEC and OSHA when work is to be performed on or near the energized equipment. Also, the program allows one to calculate initial pressure generated by arc blast and arc flash TNT (TriNitroToluen) equivalent.

 How does Arc-Flash-Analytic v 5.0 compare to other AFA software versions

  • IEEE 1584 Empirical Model calculation mode has been extended to include a circuit protection device drop-down list. The program will populate the list with protection devices meeting the application's system voltage and interrupting rating requirements. AFA v5.0 comes complete with a built-in library of selected protection devices and the capability to extend the library using customer-specific devices. The program will automatically determine arc duration based on predicted arcing current value and selected protective device type.
  • The feature above has effectively turned redundant IEEE 1584 Fuse Equations calculation mode available in previous AFA software versions and restricted to Bussmann's Class RK1 and Class L fuses, 600V system voltage, 1-1/4 inches gap between conductors and grounded switchgear equipment configuration. Similarly, IEEE 1584 LV Circuit Breaker Equations tab has also been discontinued in AFA v5.0, and both IEEE 1584 Fuse Equations and IEEE 1584 LV Circuit Breaker Equations have been removed from AFA v5.0. Consider using AFA v4.1 software if you really need to do the analysis based on IEEE 1584 Fuse Equations and/or IEEE 1584 LV Circuit Breaker Equations models.
  • Tables that appeared in section D.8 of NFPA 70E 2009 under the title "Estimated Incident Energy Exposures for Live Line Work on Overhead Open Air Systems 1kV to 800kV" no longer appear to be in new edition of NFPA 70E year 2012 standard. Therefore, Phase to Ground Arcs in Open Air calculation mode based on the section D.8 table method has been removed from AFA v5.0. Consider using AFA v4.1 software to estimate incident energy exposures for live line work on overhead open air systems per older NFPA 70E standard edition.
  • AFA v5.0 program allows to perform arc flash boundary calculations based on 1.2 cal/cm^2 (5 Joules/cm^2) onset energy to second degree burn for bare skin exposure per IEEE 1584 Guide and other incident energy levels as well, such as the rating of proposed personal protective equipment, or evaluated onset to second degree burn energy.
  • By clicking on Options -> Units menu option, metric (mm, Joules), imperial units (inches, calories) can be specified for distances ( including Gap between Conductors, Working Distance, Arc Flash Boundary, Limited, Restricted and Prohibited Boundaries ), energies ( including Incident Energy and Onset To Second Degree Burn Energy ), Arc Blast Initial Pressure and TNT Explosive Equivalent. AFA v5.0 software will "memorize" selected units of measurement and apply them next time you open up the program.
  • The new program version allows one to save equipment configurations for future reference, including Equipment Name, Equipment Type, Available 3-Phase Short Circuit Current, Gap between Conductors, System Voltage, Grounding Type, Working Distance, Upstream Protective Device and/or Arc Duration both at Predicted Arcing Current and Arcing Current reduced by 15%.
  • Create and save customized arc flash labels in English, French, Spanish, Portuguese, Dutch, German, Italian, Simplified Chinese and Ukrainian languages in electronic high resolution JPG, BMP (BitMap), GIF, TIF and PDF formats. The program features new "Warning" and "Danger" label layouts with orange, red strips on labels' top and bottom, as well as a plain background.
  • If you require alternate label layouts, or arc flash warning labels in languages other than English, French, Spanish, Portuguese, Dutch, German, Italian, Simplified Chinese or Ukrainian contact us and we will do our best to accommodate your requirements.
  • Print manager. Now you can preview, setup and print labels direct from AFA V5.0.

Additional information about AFA v 5.0 and IEEE 1584 Empirical Model that the program is built upon

The IEEE 1584 empirically derived model was chosen for arc flash analysis due to the model's capability to accurately account for a wide variety of setup parameters including:

  • open and box equipment configurations
  • grounding of all types and ungrounded
  • gap between conductors of 3 to 152 mm.
  • bolted fault currents in the range of 700A to 106kA
  • system voltages in the range of 208V to 15kV
  • working distances from 10 to 80 inches

For cases where voltage is over 15kV or gap is outside the range of the model, the theoretically derived Lee method can be applied and it is included in Arc Flash Analytic v5.0.

The calculator takes equipment configuration, gap between electrodes, grounding type, short circuit fault current value and system voltage on input, and determines arcing fault current at potential point of fault.

For protective devices operating in the steep portion of their time-current curves, a small change in current causes a big change in corresponding operating time. Incident energy is linear with time, and consequently arc current variations may have a big effect on incident energy. The IEEE 1584 proposed solution is to make two arc current and energy calculations: one using the calculated expected arc current and another one using a reduced arc current that is 15% lower.

The calculator enables calculations for both of the above considered cases. The IEEE 1584 Empirically Derived Model procedure requires that an operating time be determined for both the expected arc current and the reduced arc current. Incident energy is calculated for both sets of arc currents and operating times. Then, the larger incident energy is taken as the model result. This solution was developed by comparing the results of arc current calculations using the best available arc current equation with actual measured arc current in the test database. The calculator predicts arcing fault current for a given configuration and amount of the available 3-phase short circuit current.

Next, the incident energy, arc flash boundary, shock protection boundaries and level of personnel protective equipment are determined based on equipment configuration, arc duration and working distance.

Note how the System Summary and Calculation Results Screen displays calculation results both for predicted and reduced by 15% Arcing Current with worst case scenario values highlighted. These are the values that will be displayed on warning label once you click on [Create Label] button.

  • Calculator-style interface makes complex calculations easy to understand.
  • Provide a safer working environment by specifying the proper level of personal protective equipment. Wearing inadequate clothing is dangerous for obvious reasons, but wearing too much clothing is dangerous due to limited mobility and visibility.
  • Design safer power systems while insuring compliance with NEC 110.16, OSHA, NFPA 70E, IEEE P1584 and CSA Z462 standards and regulations.
  • Avoid potential fines, lost productivity, and increased insurance and litigation costs.
  • Evaluate Threshold Incident Energy for a Second Degree Burn.
  • Save time by generating arc flash warning labels in electronic high resolution JPG, BMP, TIF, GIF and PDF formats
  • Create warning labels in English, French, Spanish, Portuguese, German, Italian, Simplified Chinese and Ukrainian languages
  • Save input configurations, calculation results for future reference or printing.
  • Perform analysis using metric, imperial units, or a mix of both
  • Calculate initial arc blast explosion pressure and arc flash TNT (Tri-Nitro-Toluen) equivalent
