Extensible measurement socket placement optimalization with respect to the higher number of conductors
Šindler, Matěj ; Čepička, Martin (referee) ; Wasserbauer, Vojtěch (advisor)
In opening, this bachelor thesis is describing structure and basic block description of UniGear switchgear manufactured by ABB company. Then this thesis focus on current and voltage transformers and sensors often used in this type of switchgear. Main part of this thesis is dedicated to evolution and description of connector, used in connection solution of withdrawable metering unit with low-voltage compartment. Next part states the main requirements for new connector, that will replace current connector in future solution. In following part there is a list of different options for new connector with their biggest strengths and weaknesses pointed out. Then there is list of alternative placements for new connector. In final part is chosen and described new connector and its placement. This solution is valuated and backed up by created 3D models.

Transformer models for educational purposes
Beran, Vojtěch ; Ctibor, Jiří (referee) ; Pazdera, Ivo (advisor)
The aim of the bachelor's thesis is to project and realize models of transformers in Matlab and Simulink program. Projected models explain the theoretical precondition of the models. The aim is also to create manuals for models usage. The theoretical part bachelor's thesis is focused on transformer theory, which defines the properties, physical quantities, parameters and relations between them. In this part is defined transition from the basic model to models of current and voltage transformer, which forms the basis for the realization of simulations in Simulink. The next part describes vector transformation needed for modeling three phase system, defining the power, voltage and current of the transformer and for change of winding connection. Last part describes non-linear magnetic field. The practical part of the bachelor's thesis is the practical implementation of transformer models in Simulink. Realized models are models of current and voltage transformers. Each model has a form of linear and non-linear model and can work in single-phase or three-phase system. The output of simulation are values and voltage, current and power waveforms for a given load. There is a brief manual for usage for each model.
