Abstract in different language:	Dielectric materials are an essential part of all electrical devices. One of the reasons, their properties are studied, is that they are most impacted by internal and external influences during the lifetime of the electrical device. Composite materials are commonly used as a dielectric part, because of the synergy effect, when combining various components that have a positive impact to combat various these negative influences. In opposition to this, the composite material is commonly layered into thick tapes to meet device nominal voltage usage. This layering has a negative impact on some important material properties, such as dissipation factor or thermal conductivity. In recent years, using nanocomposites becomes an interesting way to improve composite materials and their reliability in electrical devices. This paper deals with the current and resorption characteristics of nanocomposite materials. These characteristics are important for understanding the influence of nanocomponent on the overall composite properties. Nanocomposite material used in this experiment was prepared by the Department of Technologies and Measurements and was consisted of epoxy resin and magnesium oxide nanoparticles. For the experiment, different values of filled nanocomposites were prepared (0, 1, 3, 5, 10, 20, 30 wt.% of MgO). Nanocomposites have been investigated by two research institutions. By this experiment, we confirmed our initial hypothesis that MgO positively influences the absorption and resorption characteristics to a certain level of filling.
