The Change in Arc Behavior by magnetic driving force acting on Arc Column

To investigate a arc behavior when the flux density linking arc current is different, two kinds of models having the different flux density with each other are proposed. Calculations of the flux density and the electromagnetic force acting on arc column using finite element method is described in this paper. And, arc behavior photographs by the high speed camera are illustrated at breaking DC 100V, 100A on the resistance load. So, the arc driving forces are compared with according to the arc types.
