摘要：
The propagation aspects of a creepage discharge in transformer oil are observed simultaneously and in detail under a positive impulse voltage condition, by means of a high-speed Schlieren optical system, a LED current measurement system and a charge measurement system by capacitor. In the present paper, the influence of the material type, the thickness of insulating barriers on the propagation of the impulse creepage discharge is especially discussed for a point to plane electrode geometry. In addition, the influence of a barrier surface to the electric field direction on the propagation of the impulse creepage discharge is also discussed for a parallel plane electrode gap with a protruding point.
