ABSTRACT

Instability of liquid dielectrics surface, being developing after the action of an alternating current corona discharge pulse, has been experimentally investigated. Voltage amplitude on the corona electrode reaches 70 kV, frequency is 17 MHz, and pulse duration is 0.5-1 μs. This is similar to rose-window instability at electrode height above the liquid surface > 5-10 mm. At lesser heights, development of a singular crater is observed with turbulization of its walls surrounded by radially divergent wrinkles on the surface. In this case, instability shape is similar to an oculus. Maximum effect is demonstrated by oils with high specific electric resistance.
