Abstract
A theoretical study and computer analysis of the cathode spot of a unipolar arc was conducted. The underlying theories of Plasma Physics, Space Charge Effects, and Electron Emission needed for an understanding of cathode phenomena are presented. Two models of unipolar arcing are reviewed and an analysis of the cathode spot is begun. A stationary model of the cathode spot is formulated with a system of equations that is not closed. A method of solution, using the Steenbeck Minimum Principle, is utilized and a computer program developed to determine the cathode spot parameters. Results of the analysis are presented for arc currents of 100, 150, 175, 200, 300, and 400 Amperes. It is found that for copper stable arcs occur only for arc currents greater than 200 Amperes.
