要約(英語): Decomposition gases due to partial discharge (PD) conditions in an oil-impregnated paper insulation system with an oil gap were experimentally investigated. Sheets of oil-impregnated paper were sandwiched between parallel plane electrodes. An oil gap was made up by overlapping sheets of oil-impregnated paper with a hole. Insulating oil was taken from the oil gap after PDs were generated in the short or long duration, and the dissolved gas analysis was conducted. As a result, it was revealed that there was a difference in the ratio of each gas volume to the total volume of gases. The ratios of H2 and C2H2 were higher than those of other gases in short duration cases, while the ratios of H2, CH4 and C2H6 were higher than those of other gases in long duration cases. PDs occurred through the insulating oil in the short duration cases. On the other hand, PDs occurred in gases in the long duration cases. The result suggests that the difference of main decomposition gases in two cases is due to the difference of the place where PDs occurred.
