Abstract
Conference Title: Conference on Electrical Insulation & Dielectric Phenomena — Annual Report 1983 Conference Start Date: 1983, Oct. 16 Conference End Date: 1983, Oct. 20 Conference Location: Buck Hill Falls, PA, USA This paper emphasises experimental results of DC conduction current in aged transformer oil using point-plane configuration. The effects of oil dehydration and filtration, anode material and field strength are investigated and discussed. It is found that i-t and i-E characteristics display exponential “behaviour and tunneling phenomenon, respectively. Moreover, sample preparation and anode/liquid interface play an important role in explaining the mechanism of DC conduction under non-uniform high field.
