Impulse breakdown of liquids
WitrynaIt is seen that the amount of metal particles under the impulse voltage reduces the breakdown voltage more, especially when copper particles are used, after a threshold value of 10% for positive impulse voltage and 20% for negative impulse voltage. ... By adding only copper nanoparticles to this liquid, the breakdown voltage drops to … Witryna31 paź 2024 · As was explained before, the main aim of the present study is to analyze the dielectric behavior of Kraft paper samples impregnated with several insulating fluids, and to compare the AC and impulse dielectric strength results obtained on NF-impregnated paper samples with those obtained for MO-impregnated specimens.
