The Science of Arcs and Arc Flash
Abstract: This presentation will cover the
physics of high current arcs, the conversion of electrical
energy into other forms of energy, and the hazards presented to the
nearby worker by this energy. First, based on the known physics of high current arcs, the creation, energy
conversion, and extinction of high current arcs will be discussed. The focus will be on 50/60 Hz AC, DC,
and impulse arcs. The differences in growth, energy conversion, and extinction will be explored for
the various waveforms, based on the published analytical models and empirical data. Energy
conversion from electrical energy feeding the arc to thermal, acoustical, kinetic, magnetic, and electromagnetic
(e.g., UV, visible, and IR) energy will be discussed. The key issues of the hazards of arcs, arc flash, and
arc blast will be presented and discussed. The various analytical and empirical methods for
estimating the electrical hazards presented by these various arcs will be summarized. Finally, the unknown
areas, ripe for further research, will be presented and discussed, particularly for DC and impulse arc
hazards.
Learning Objectives: Attendees will gain
knowledge of the state of the art of scientific and engineering knowledge of the arc flash phenomena in electric power systems.
Instructor: Lloyd B. Gordon, PhD, Los Alamos National Laboratory
