Influence of Electrode Coatings on Conduction Currents in Transformer Oil

Nature volume 199, pages 1082–1083 (1963)Cite this article

Abstract

ALTHOUGH the exact mechanism of conduction in dielectric liquids is still the subject of controversy, it has long been recognized that the surface state of the electrodes greatly influences the conduction process1. Recent experimental evidence2,3 has shown that this conduction process is very sensitive to the surface state of the cathode, in particular to the presence of an insulating oxide layer. While it is known that oxide layers on the anode influence the electric strength of liquids4, the influence of anode surface barriers or films on the conduction currents does not appear to have been studied.
