ETAP Arc Flash Analysis software brings you new and enhanced capabilities which allow for faster and easier assessment of arc flash hazards and incident analysis. Identify and analyze high risk arc flash areas in your electrical power system with greater flexibility by simulating and evaluating various mitigation methods in your arc flash study.

The Arc Flash Analysis program is a completely integrated module that solves multiple scenarios to determine worst-case arc flash energy levels. The Arc flash calculation software module also produces professional reports and high quality arc flash safety labels at a press of a button.

The Arc Flash Analysis module also includes comprehensive single phase and three phase arc flash assessment calculations as well as an invaluable arc flash analyzer tool to summarize results from the arc flash study.

DC Arc Flash is offered as a separate module for direct current applications.
