| Abstract: | ALTHOUGH THERE HAVE BEEN A FEW MEASUREMENTS OF DIELECTRIC BREAKDOWN IN NANOSECOND PULSE, THE BASIC NATURE OF THE MECHANISM OF DIELECTRIC BREAKDOWN IS STILL A LOT OF DISPUTES. IN CONNECTION WITH THE DEVELOPMENT OF HIGH SPEED SWITCH AND PULSED POWER TECHNIQUES, WE HAVE OCCASION TO MEASURE SOLID AND LIQUID BREAKDOWN CHARACTERISTICS IN A SHORT PULSE WITH HIGH ELECTRICAL FIELD. IN THIS PAPER, BREAKDOWN CHARACTERISTICS OF TRANSFORMER OIL, CASTOR OIL, POLYIMIDE FILM AND POLYESTER FILM HAVE BEEN INVESTIGATED. THROUGH THE EXPERIMENTS, WE GET A LOT OF DATA AND SOME RULES AMONG PULSED STEEP, BREAKDOWN FIELD AND BREAKDOWN TIME. THE EXPERIMENT RESULTS INDICATE THAT DIELECTRICS BREAKDOWN CHARACTERISTICS IN DC AND AC ARE DIFFERENT FROM THAT IN NS LEVEL HIGH VOLTAGES PULSED. |
