Breakdown Voltage Measurement of Solid and Liquid Dielektric Materials
Ryšavý, Tomáš ; Pelikán, Luděk (referee) ; Krbal, Michal (advisor)
This thesis aims to theoretically describe the formation of electric breakdown in solid and liquid dielectric materials and subsequently focuses on the measuring itself. In addition to describing the standardized procedure of electrical breakdown or breakdown voltage of dielectric materials, this paper also focuses on the most important parameters and conditions that affect the electric strength of materials. This thesis also includes designs of electrode systems and test chambers for measuring solid and liquid dielectrics.

Determination of moisture content in electrical insulating materials
Šebesta, Petr ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
This work is based on determination of moisture content in electrical insulating materials materials and ways to measure the moisture. In the theoretical section describes the methods of thermal analysis, and subsequently described in detail Thermogravimetry method, which is used in the measurement. Measurements are made using the Moisture Analyzer RADWAG 60 W/H connected with a PC, using a variety of samples from inorganic to organic. A great variety of samples was chosen because of demonstrations thermogravimetric methods and a better understanding of wetting and drying of different materials.
