The paper presents the results of measurements of electrical strength of Midel 1204 natural ester doped with iron nanopowder in a hydrophobic carbon shell. The research was conducted for different concentrations of the dopant. The samples were prepared in the High Voltage Technique Laboratory. After mixing, they were tightly closed, and the first measurements were taken after 5 weeks of dissolution of the dopant in liquid. The tests were repeated after another 2 weeks and 3 weeks of dissolution of nanoparticles. An increase in both mean and maximum breakdown voltage was shown for the tested liquid mixtures. The concentration for which the value of electrical strength begins to decrease was indicated. It was also shown that a longer time of dissolution of nanoparticles causes an increase in the electric strength value for the tested samples.
本文介绍了掺杂有疏水碳壳包裹的铁纳米粉末的米德尔1204天然酯的电气强度测量结果。针对不同浓度的掺杂剂进行了研究。样品在高压技术实验室制备。混合后，将其紧密密封，在掺杂剂在液体中溶解5周后进行首次测量。在纳米颗粒溶解另外2周和3周后重复进行测试。测试的液体混合物的平均击穿电压和最大击穿电压均有所增加。指出了电气强度值开始下降时的浓度。还表明，纳米颗粒溶解时间越长，测试样品的电气强度值越高。
