Calculating hazards

This article presents an improved method that uses time-domain analysis to calculate arc-flash hazards. The time-domain analysis allows current limitation by fuses and other effects to be studied. The ordinary differential equations for the three-phase circuit and any current-limiting fuses are solved by fourth-order Runge Kutta integration with automatic control of the time step.
