Preliminary study of the breakdown characteristics of the pressurized deionized water under short pulse voltage

The bubble breakdown theories of liquid that summarizes of the experimental data of the Siberian Research Institute of Energetic in Russia is presented in this paper. The breakdown experiments of the water switch have been done under the two short pulsed voltages of 1 μs and 300 ns.Some valuable experimental data about the relations of the breakdown electric field intensity and the hold-off time of pressurized deionized water breakdown have been acquired. The experimental results indicate that the breakdown electric field and the hold-off time of pressurized deionized water is enhanced under the two short pulsed voltages, when the pressure of water between the electrodes increases. However, the effects of water pressure is different under the short pulsed voltages of 1us and 300 ns; Short
