Flash intensity of arc, iso-flashes distribution and body surface area

The empirical model of IEEE Standard 1584 defines Arc Flash incident energy and arc-flash boundary. This paper assumes as reference the empirical model that compares with the spherical model of the incident energy emission and classifies the deviations. The new approach allows a physical approach to the phenomenon, to identify characteristic parameters as the arc flash intensity, and to analyze the distribution of the incident energy applying the "point by point" method on flat surfaces exposed to arc flash, as a simulation of the human body. This method allows determining isoflash surfaces that collect points at different distances in the space, allows characterizing the behaviors of electrodes configurations and estimating the prospective Body Surface Area affected by lesions
