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.

Dielectric absorption of varnish composites
 Reňák, Ladislav ; Frk, Martin (referee) ; Rozsívalová, Zdenka (advisor)
This work deals with issues of electro insulating varnishes and composite materiále within the frame of dielectric changes depending on a change of relative humidity where these varnishes are located. For this purpose had been created variety of a samples of electroinsulating varnish with different percentage of filling with mica. The general aim is acquire information about dielectric changes of examined electro insulating varnishes that are exposed to atmospheric influence.
