Determination of the characteristics of an electric arc plasma contaminated by vapors from insulators

Results are presented from an experimental study (at atmospheric pressure) carried out on plasma penetrated by vapors from different industrial insulators. The data describe the influence of each insulator type upon the characteristics of the electric arc plasma, i.e. the resulting increase of the temperature, electronic density, electric field, and extinction velocity of the arc. Measurements were made spectrometrically and by means of probes.<
