Electrical conduction of alternative electroinsulating liquids
Reňák, Ladislav ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
This labor deals with features of alternative electrical insulating liquids and also petroleum-base liquids. It examines their usage in the electrotechnical industry. The practical part of the thesis deals with measurement of absorption charakteristics of biodegradable electrical insulating liquid MIDEL 7131 and the petroleum - based transformer oil TRAFO N. The results of the measurement are examined by the help of substitutional math function.

Influence of nanoparticles on the properties of electroinsulating materials
Sedláček, Michal ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
This work deals with influence nanoparticles, as fillers of polymer, to electrical properties dielectric composite materials. Addition of just a few weight percent of nonofillers has profound impact on the physical, chemical, mechanical and electrical properties orf polymer. Simultaneously is focused on production and diagnostics by the relaxation spectroscopy and measure internal resistance. Examination material is epoxy resin TSA 220S filled Al2O3 and SiO2 nanoparticles.
