Abstract

Arc-flash is a dangerous phenomenon that can occur during an arcing fault in an electrical system. People nearby may be subjected to extreme heat, light, pressure, and sound. Research regarding arc-flash has focused primarily on AC arc-flash due to the prevalence of AC electricity in the grid. However, the grid has begun to integrate more DC electrical sources as a result of decentralization efforts and environmental concerns. The increased proliferation of DC electrical sources demands research into DC arc-flash to assess the hazard as low-voltage DC sources have already become commonplace. Some DC arc-flash models have been produced to estimate incident energy. These models are either theoretical or semi-empirical in nature, as empirical research pertaining to DC arc-flash is scarce. The lack of empirical DC arc-flash data inspired a series of tests at American Electric Power’s (AEP’s) Dolan Technology Center (DTC) that were conducted in August 2018. These tests allowed the development of a limited empirical equation for incident energy. The research presented in this thesis is a continuation of the August 2018 DC arc-flash testing with the objective of generating an expanded incident energy equation. Furthermore, this research seeks to address the effects of some atmospheric conditions on the behavior of low-voltage DC arcs.
