Radial distribution of current density and temperature in a heavy‐current stabilized arc column in SF₆ gas

Analytical similarity between stabilized arc characteristics and transport properties in gases

“…1. 1 [9]. 1 can be divided into three regions; 0 low-temperature region, 0 intermediate region and @ high-temperatuE region.…”

“…In contrast, the authors [9][10][11] have analyzed the arcing in SF6 gas by considering the radial distribution of conductivity inside the conductivity radius. To analyze the arc characteristics, the coefficients C and TJ of Eq.…”

“…Ers v c /~s = ( z &~~s v c c 2 )~ (21)The E-Ia curve of a stabilized arc moves in the -45" direction in the log-log plot when the a r c radius rs increases[9]. Equation (21) indicates that JCT has the same kind of effect on the E -k curve.According to Eq.…”
