CURRENT-VOLTAGE CHARACTERISTICS OFA THREE-PHASE ONE-CHAMBER ALTERNATING CURRENT PLASMATRON V. B. Kovshechnikov UDC 537.523 A method for the determination of the current-voltage characteristics of a one-chamber three-phase industrial-frequency plasmatron is considered. The form of the characteristics is set proceeding from general laws governing a gas flow past an arc; a numerical value of the coefficients entering these characteristics is calculated with account of the data obtained in the experiment.
