We sought to establish a model that predicts the conditions under which the arc was extinguished. During the study group we attempted to show how an equation of state could be derived by proposing that the arc should be in thermal equilibrium with the surrounding gas. The behaviour of the system as the current goes to zero was examined but no firm conclusions could be draw. date: 1990 citation: Breward, C.J.W. and Chapman, S.J. and Lacey, A.A. and Ockendon, J.R.
