The surface flashover phenomenon of solid-liquid interface in transformer oil has a serious in-fluence on the insulating performance of electrical devices. Therefore, many studies on the surface flash-over of insulation dielectric in transformer oil were paid attention to. The current experimental and mea-surement methods were introduced, and the flashover characteristic under the condition of nanosecond pulse was focused on. The research situation of the effect of component of transformer oil, voltage wave-form, insulation structure, dielectric property of solid dielectric, and etc. factors on the surface flashover was reviewed, and the surface flashover process and some empirical formulas were presented. Finally, some difficult problems that urgent to solve for surface flashover of insulation dielectric in transformer oil were proposed.
