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.

Degradation of liquid insulators for high voltage
Komárek, Filip ; Štěpánek, Jaroslav (referee) ; Krbal, Michal (advisor)
This bachelor's thesis deals with measurement of liquid insulators. Mainly it deals with diagnostic tests of transformer oil. Diagnostic tests are needed to identify oil status and to determine the parameters of the oil. The status of the used oil determines its type of degradation and progress of degradation. For the determination of degradation it is necessary to know the composition of the essential oil, to determine how it has changed the structure of the oil and the oil did not contain before use. To determine the basic electrical properties of the oil are used in diagnostic tests such as dielectric strength and dissipation factor. This work is in addition to a summary of diagnostic tests observation of mineral oil with an unknown degree of degradation and behavior of impurities in mineral oil once the electric field.
