Calculation of Temperature Profiles of Radial Conduction Dominated Arcs

Switching technology,SF6 alernative gases,material properties

This study aims to establish a theoretical understanding of the causes for different arc column sizes in different gases, such as in air and SF₆.  It has been found that for low current arcs in strong axial gas flow, the radial temperature profile of the arc column is dominated, among different cooling mechanisms and properties, by the energy density of the gas as a function of temperature.
