Single and three-phase arc flash calculations software

ARCMASTER version 1.0 software for Windows operated PCs has been developed as an easy to use and comprehensive tool for calculating arc incident energy and arc flash boundary. This software simplifies determining incident energy at working distance, arc flash, limited and restricted approach boundaries in single phase and three phase AC power systems when work is to be performed on or near the energized equipment. The program performs the analysis by taking into account equipment class, fault type, system voltage, available short circuit fault current and X/R ratio, conductor gap, working distance, protection device type and rating, or a preset arc duration value, and determines incident energy released by the arc flash, arc flash and shock protection boundaries and site-specific level of personal protective equipment (PPE). ARCMASTER V1.0 is applicable for systems with voltages in the range of 50 to 30,000V AC, short circuit fault currents from 0.2 to 50kA, the fault X/R ratios from 0 to 50, conductor gaps from 1 mm. up to the lesser of 300 mm. and the maximum value where the arc can likely be sustained under the specified system voltage, available short circuit fault current and the fault power factor.

ARCMASTER V1.0 takes equipment class, fault type, system voltage, available short circuit fault current and X/R ratio, conductor gap, working distance, protection device type and rating, or a preset arc duration value, and determines incident energy, arc flash and shock protection boundaries. Arcing current can be expressed as a function of the length of the gap and arcing voltage. Arcing voltage can be derived as a function of arcing current, system voltage, available fault current and the fault X/R ratio. ARCMASTER V1.0 calculates arcing current using the iterative method by cycling through the equations for arcing current and arcing voltage until the answers converge. Next, the program will determine the arc duration based on protective device time-current characteristics and circuit time-constant. Lastly, the program will calculate incident energy at working distance, arc flash and shock protection boundaries. Check AC Arc Flash Modeling for more information. ARCMASTER V1.0 comes complete with a built-in library of selected protection devices and the capability to extend the library. The program will determine arc duration based on predicted arcing current value and selected protection device type and rating.


Additional information about ARCMASTER V1.0 software program

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), incident energies.

The program allows saving equipment configurations for future reference, including equipment name and class, fault type, total available short circuit fault current and power factor, part of the available fault current through protection device, gap between conductors, system voltage, working distance, upstream protective device information and arc duration.

ARCMASTER V1.0 performs arc flash boundary calculations based preset or on evaluated onset to second degree burn energy.

Create and save customized arc flash labels in English and a number of 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.


  • 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 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, print, save warning labels;
  • Save equipment data, calculation results for future reference or printing;
  • Perform analysis using metric, imperial units, or a mix of both

System Requirements

ARCMASTER V1.0 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). The program requires Microsoft .NET Framework Version 3.5 or higher to run. If you experience problems running ARCMASTER V1.0 once you install it on your PC, please check the link below to identify .NET version set up on your system:

Determining Which Version of the .NET Framework Is Installed

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 ARCMASTER V1.0, contact us and we will assist you in identifying and resolving the problem.
