Nano-MgO particles were added in epoxy with particle weight ratios of 1, 3, 5, 7 wt%. Tracking experiments were carried out by using dc voltage. The tracking process was recorded by a high speed camera. The relation of tracking failure with the adding rate and applied voltage was investigated. Obtained results indicated that with increasing adding rate from 0 to 5 wt%, number of drops needed in tracking...
Moisture in oil-immersed transformer will become small bubbles suspending in insulation oil at high temperature. In order to investigate the influence of suspending bubbles on tracking failure of oil-impregnated pressboard in oil-paper insulation, a model based on needle-plate electrodes was established. This model was used to study effect of the number of suspending bubbles generated by dropped distilled...
