Ako impregnant bol použitý rastlinný repkový olej, nakoľko je biologicky odburateľný a jeho použitie pre elektrotechnicke ucely by bolo ekologicky prijateľne. Na porovnanie elektrických vlastnosti impregnovanej papierovej izolacie a rastlinneho impregnanta sa použilo meranie stratoveho ciniteľa, permitivity a meranie elektrickej prieraznej pevnosti. In this article we compared the results of measurements of electrical insulating properties of oil-paper insulation with a separate oil insulating. Colza oil was used for impregnation of paper insulation because natural oil is biodegradable and its using would be environmentally accepted . The measurement of dissipation factor, permittivity and electrical strength were used to compare the properties impregnated paper and liquid natural oil.
