Surge arresters, their construction and use in power system
Novický, Marek ; Pelikán, Luděk (referee) ; Orságová, Jaroslava (advisor)
The bachelor thesis deals with the means used to protect the equipment from the effects of overvoltage. The first of the thesis outlines basic information regarding the used overvoltage protections in the distribution system. The thesis also features the practical part outlining measurements carried out on the surge arrester. The last chapter deals with the dimensioning of the surge arrester in the high voltage distribution system.

Solving problems of CD and PMD in optical networks
Motúz, Rastislav ; Šifta, Radim (referee) ; Filka, Miloslav (advisor)
The aim of this bachelor’s thesis is to analyse dispersions which are affecting a high-speed transfer in optical systems. It is focused on chromatic – CD and polarisation mode – PMD dispersion. It is devoted to definitions, limit values, methods of measurements and compensation methods against disturbance to the final quality of transmission. The thesis is divided into the three-chapter long theoretical part and the practical part which contains two chapters. The results of the extensive experimental measurements done by CD/PMD tester – modular platform EXFO FTB-200 are stated in the practical part and partly in the Appendix too. The output of the measurement confirms the theoretical assumptions stated in the theoretical part and thus proves the aim of the thesis to be achieved.
