Simple theory of free-burning arcs

Webb1 aug. 2024 · An 800 A free-burning arc sustained for about 48 ms, whereas a 315 G field interrupted it within 8 ms. The information found on arc-root diameter and current density of 80-800 A free-burning arcs in air has filled a gap of data found in the literature. This information, in turn, will help to improve the theories available on free-burning arcs.
