摘要：

Abstract: Methods for increasing energy efficiency in the electrical-power-supply systems of arc plasma treatment facilities, as well as general characteristics characteristic of the arc process that affect electric-power quality, are considered. The structure and general principle of operation of an experimental electric-arc unit are described. Data on changes in such characteristics as active, reactive, and full power; total harmonic voltage and current distortion; and voltage deviation, as well as the level of higher-harmonic current distortion, are systematized and analyzed. Each of the experimental unit characteristics depending on the arc operating current are established on an empirical level. The main relationships are presented by means of which, based on empirical dependences, an energy-efficient unit-control system could determine the active energy loss in the power-supply lines of the unit originating from decreasing electric-power quality. © 2021, Allerton Press, Inc.
