Design the Transformer Station for the Outgoing Power of Cogeneration Unit
Pastorek, Jaroslav ; Procházka, Aleš (referee) ; Orságová, Jaroslava (advisor)
The thesis deals with the design of a transformer station for the outgoing power of cogeneration unit with an electric capacity of up to 1 MW. The thesis describes the design procedure of individual devices such as a transformer with a nominal ratio 22/0,4 kV, high voltage switchgears and low voltage switchgears. With the proper selection of the transformer, along with the technical parameters, the economic benefits that come from its purchasing and operating costs with the transformer operation are also considered. Based on this, the economic comparison of selected types of oil transformers during 20 years is also developed. Another part of the thesis deals with HV and LV switchgears, which are dimensioned according to shortcircuit conditions in the transformer station. In conclusion this work deals with the grounding of a transformer station and design protection in accordance PPDS.

Calculation and measurement of disconnecter temperature
Šimek, David ; Dohnal, Petr (referee) ; Bušov, Bohuslav (advisor)
Bachelor‘s thesis is focused on the theoretical analysis of heating of electrical wires, electrical contacts and current necking in electrical apparatus. This bachelor’s thesis contains complete practical calculation of disconnector. The main part of work is experimental measurement of disconnector warming. The thesis points on possible causes of deviations between calculated and measured values.
