Draft controlled modular source 6,3kA / 5VAC for warming trials and tests breakers
Zolich, Ladislav ; Dostál, Lukáš (referee) ; Dohnal, Petr (advisor)
The main object of this thesis is to design a toroidical transfomer on the given parameters. Project is focused on learning about principles of transformers, it’s designing and mainly on designing the given transformer. Designing contains material selection of the core of the transformer, its size, then calculating magnetic flux, no-load current, cross-section of conductor and calculating no-load losses and joule losses. The next part is designing the mechanical parts of transformer, its terminal plate, base and cooling system. Thesis is also mainly focused on designing the form for potting the transformer in epoxy resins. In the end is measurement and form of powering the transformer.

Optimization of Selection of type of the supplying transformer of net 22 kV, dedicated for output power of solar power plant
LÍSAL, Jakub
This bachelor thesis deals with choosing the optimal transformer considering the supposition and measured data. The first part contains description of functioning of the transformer and its working states, including the mathematical expression, as well as description of the transformer's construction and mentions various uses of the transformer. In the second part the optimal transformer for power extraction from photovoltaic power plant is chosen based on losses created during unsymmetrical load. The amount of created losses and the cost of the transformers is considered during the choosing.
