摘      要：An experimental study of the inception of the first‐mode negative streamer at liquid/solid interfaces is presented in this *** study is performed with a point‐plane configuration under square high voltage *** electrode configuration is immersed in mineral oil and the liquid/solid interface is assembled in contact with the point electrode or in its *** polymers and two impregnated papers have been tested as solids of the liquid/solid ***,it is possible to compare the influence of different parameter of the solid and the interface on the streamer *** example:Permittivity,solid surface roughness,chemical composition,*** has been observed that streamer inception voltages at interfaces with solids of higher permittivity to that of the mineral oil are statistically ***,streamer inception voltages of streamer initiated free in the oil(no liquid/solid interface)are similar to that of the inception voltage of cases with solids with high *** contrast,the inception voltage of streamers initiated at permittivity matched interfaces are shown to be highest of the *** streamer inception voltage is also studied for different distances be-tween the liquid/solid interface and the point electrode with a permittivity matched *** results show a dependency of the inception voltage and the distance be-tween the point electrode and the ***,an analysis of the observation is performed to show that the Townsend‐Meek criterion cannot predict the obtained results.
