Abstract

Electric conduction in transformer oil is significantly affected by the presence of a solid/liquid interface. Using a blade-plane electrode geometry, the influence of an insulator inserted along the plane of symmetry of an electrode gap on conduction currents in transformer oil was investigated. Although the stationary relationship between current I and voltage V always showed linear plots of V versus I^&frac13;, conduction currents were prominently decreased by the presence of the insulator. This reduction of current is discussed based on electrohydrodynamic (EHD) motion and the electric field of the blade edge, taking the insulator surface charging into account. © 1998 Scripta Technica, Electr Eng Jpn, 123(4): 1–7, 1998
