要約(英語): Insulation behavior of small-air-gap for the molded insulation system has been investigated by comparing the well-known Paschen curve. Three electrode systems Metal-Gap-Metal (MGM), Metal-Gap-Insulator (MGI) and Insulator-Gap-Insulator (IGI) were employed as the test samples. It was found that Vs (breakdown voltage of the air gap) of the MGM were higher than the conventional Paschen curve, which can be attributed to the lacked initiating electron for Vs. This behavior was also obtained for MGI and IGI system. However, X-ray irradiation gives the remarkable effect on these Vs resulting in the coincidence to the Paschen data. According to the references' data-review and some experimental data for Paschen minimum region, new fundamental and universal Paschen curve for the solid insulation system was proposed.
