Influence of oil parameters and pressboard mass density o dielectric response of oil-paper insulating

The first part of the article presents dielectric response in frequency domain of aged oil-paper samples. Then, the samples were vacuum dried and the aged oil was extracted from the paper. In the end the dried paper was impregnated by new and dry oil. In each mentioned stage of investigation the dielectric response and moisture content in paper were measured. In the second part of the article the influence of mass density of moistured and impregnated pressboard samples on their dielectric response was discussed.
