Abstract

The model of current distribution in arc roots comprising dotted current emitting sources is proposed. A new approach to the potential boundary conditions is discussed. The paper presents the qualitative analysis of the arc motion based on the electrical field model described. The main result is the dependence of arc motion characteristics on the arc root location on the electrode. The three regions of arc motion, the zone of accelerated arc motion, the zone of arc deceleration, and the zone of arc erosion are found. Results of modeling agree with experimental data
