Methods of analysis of vibration signals
Russ, David ; Hájek, Vítězslav (referee) ; Janda, Marcel (advisor)
The main target of this master’s thesis is to focus on methods of analysis of vibration signals in electric machines. To get know the basic principles of the diagnostics methods, is important to clarify origin of the vibration signals and the impact they have. The selected methods were tested practically by measurement on electric machines. Measured data were processed in program LabVIEW. In this thesis were created programs which actually can be aplicated for complete vibrodiagnostics of electric machines in particular induction motors. The basic evaluation of vibration are the RMS value, Crest factor, time course and power spectrum. Results of this thesis are used to demonstrate how quickly and effectively can be vibration signals from electric machines evaluated.

Parameter analysis of single-phase transformer
Russ, David ; Mach, Martin (referee) ; Cipín, Radoslav (advisor)
The aim of Bachelors thesis is to focus on the principle of a transformer using finite element method. I will focus on single-phase transformers with low power. On the specified types of transformers are made complete proposal of individual parameters, which are then compared with the results simulated using program. In ANSYS Maxwell were 2D models created according to the real transformers and subsequently simulated their behavior under no- load and short-circuit. In conclusion the mutual comparison between different types of transformers.
