Outline of Final Research Achievements

Epoxy/silica nanocomposites were prepared and its withstand voltages of impulse creeping discharge in insulating oil were evaluated. As a result, the withstand voltage increases by 10% with 1 wt% addition of nano-silica. On the other hand, it decreases by 10% with 10 wt% addition of nano-silica as compared with the specimen without nano-silica addition. An effect of this improvement might be related to an electronic carrier trap of nano-particles.
From results of the secondary electron emission measurement, it is found that the secondary electron emission coefficient is slightly suppressed in the nano-silica added specimen. From results of quantum chemistry calculations, it is found that nano-particles show a functionality as deep traps. These results may contribute to understand the improvement mechanism of the breakdown strength and the creeping discharge withstand voltage.
