Fast Transient Phenomena in High Voltage
Vala, Martin ; Dohnal, Petr (referee) ; Krbal, Michal (advisor)
This work deals with research and description of the fast transients in high voltage technics. First part deals with division of fast transients and description of an impulse wave properties. Second part is focused on atmospheric overvoltage description and on direct and indirect lightning surge protection methods. Next, there are described the main characteristics and division of the surge protection devices in the work. In the next part, there are introduced some sort of high voltage generators, used for meassurement of impulse wave in a transmission line. In the last part there is stated an analysis of practical measurement of impulse weaves and surge arresters by using a Marx generator.

Wave propagation in homogeneous line
Brázda, Daniel ; Steinbauer, Miloslav (referee) ; Friedl, Martin (advisor)
This work deals with the propagation of electromagnetic waves. In the theoretical section describes the propagation of waves in the open space and the line. The main objective of this work is to design a new layout laboratory exercises in which students measure the behavior of waves on a homogeneous line. The design include measuring the standing wave ratio (SWR) using the digital SWR meter, measure the voltage measured along the line and measuring the frequency dependence of the input impedance of the line.
