Arc Flash Analytic (AFA) software and mobile apps have been developed based on NFPA 70E Standard for Electrical Safety in the Workplace and IEEE 1584 Guide for Performing Arc-Flash Hazard Calculations as easy to use and comprehensive instruments for calculating arc incident energy and arc flash boundary, for determining limited, restricted, prohibited approach boundaries and hazard levels required by NEC / CEC and OSHA when work is to be performed on or near the energized equipment. Also, the AFA V5.0 software for Windows operated PCs allows one to calculate initial pressure generated by arc blast and arc flash explosive equivalent.
NOTE: System voltage text box was deactivated and the value was set to 208V AC in unregistered / free version of AFA V5.0
Arc Flash Analytic program is now available by mail in disk format or via download from our web server. Payments can be made online using Visa or MasterCard credit card, through PayPal or any other acceptable payment form. The installation package and the individual product registration credentials will be sent to you within 24 hours of placing your order. We offer money-saving bundles of programs. If you bundle Arc Flash Analytic (AFA V5.0) program with ARCAD SCA V1.0 short circuit software you will pay less than purchasing the programs separately.
AFA mobile can be downloaded, installed and used for free. The free AFA mobile version is limited to 208V systems only but fully capable otherwise. There's an optional in-app 'Pro Upgrade' purchase available for $199.99. The upgrade will unlock system voltage box for the voltages in the 208 to 46000V range.

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:
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.
Arc-Flash-Analytic 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.
Arc-Flash-Analytic 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.
AFA V5.0 was written in C# programming language, best viewed as a descendant of both C++ and Java languages. The language was developed by Microsoft within its .NET initiative and later approved as a standard by ECMA (ECMA-334) and ISO (ISO/IEC 23270:2006). AFA V5.0 requires Microsoft .NET Framework Version 3.5 or higher to run. If you experience problems running AFA V5.0 once you install it on your PC, check please if you have .NET Framework Version 3.5 or higher installed on your PC system. To see which versions are installed, view the %WINDIR%\Microsoft.NET\Framework directory. (You should also view the Framework 64 directory on a 64-bit computer, which can have 32 or 64-bit versions installed.) Each version of the .NET Framework has a directory, and the first two digits of the directory name identify the .NET Framework version; for example: v1.1.4322 for the .NET Framework 1.1, v3.5 for the .NET Framework 3.5, and so on.
If there is no Microsoft .NET framework installed on your system, or the installed .NET framework version is less than 3.5, please follow the Download .NET Framework Version 3.5 link to update your system. Should you encounter any problem installing or running AFA V5.0, contact us and we will assist you in identifying and resolving the problem.
