Though the electrical destruction of liquid insulator as transformer oil is supposed to be promoted by a corona originale in oil, the mechanism of this destruction is made differences by the state of this initiating streamer corona. In this paper, I will write what I studied the method of supplying voltage by Lichtenberg's figure, on other word how the destruction in oil is made by the number of supply, time length of voltage, etc. But here, I especially treat only the case of destruction by positive discharge in direct current and positive impulse voltage.
