F. Pontiga et A. Castellanos, THE EFFECT OF FIELD-ENHANCED INJECTION AND DISSOCIATION ON THE CONDUCTION OF HIGHLY-INSULATING LIQUIDS, IEEE transactions on dielectrics and electrical insulation, 3(6), 1996, pp. 792-799
A generalization of the Thomson model to include field-enhanced dissoc
iation in the bulk (the Onsager effect) and unipolar charge injection,
without recombination between electrolytic and injected ions, is form
ulated for nonpolar dielectric liquids. In the case of an autonomous i
njection of charge, approximate analytical solutions are given for the
dissociation and the injection current densities. A comparison with t
he 'exact' numerical solution is done to determine the regions of vali
dity of the approximate solutions. The general case of field-enhanced
dissociation and nonautonomous injection also is investigated numerica
lly.
