Evaluation of economic efficiency of investments to the distribution grid in terms of regulatory environment
Oravčok, Ján ; Vybíral, Pavel (referee) ; Radil, Lukáš (advisor)
The first part of the thesis has a research character and solves the financial flows in order to evaluate the economic efficiency of investments in the distribution system. The next part describes the origin and principles of regulation in the electricity market in the Czech Republic. In the second part, the thesis deals with the calculation of the economic efficiency of the investment according to the Energy Regulatory Bulletin on a concrete example of the renewal of the external cable line in Telnice. Part of the thesis is also a comparison of the external and cable lines in terms of running costs. The conclusion explores the impact of the renewal of the power line on its operating costs in the distribution system of the Czech Republic.

Radar antenna diagnostic module
Pacner, Petr ; Urbanec, Tomáš (referee) ; Kubíček, Michal (advisor)
Faults like open and short circuit in electrical wirings pose a significant threat on functionality of the whole application. This thesis describes conceptual design of a fault identification module for coaxial cables between transmitter and antenna in radar systems, and focuses on faults localization. The main goal is to select from existing a suitable method for such faults analysis and create a demonstration module serving as a basis for further development. This contains theory regarding basic classification of wiring faults and principles of frequently used detection methods including some of their prameters, advantages and disadvantages which altogether build a foundation for method selection. The chosen method is analyzed by simulations and further on laboratory equipment controlled by a set of computer applications. In the end the chosen method is implemented on a development kit, which is then used for measurements of wire sample.

Design of the implementation project for house's electrical installation
Pitron, Jiří ; Drápela, Jiří (referee) ; Mastný, Petr (advisor)
The thesis deals with the design and process implementation project for house's electrical installation. The first section contains a statement of the necessary legislation, which is intended for the proper construction of the project. The following are practical examples on how to connect the object to the distribution network, basic furnishing and electrical wiring protection, design of electrical distribution lines and zone location. Continuing this part of the object is to provide external and internal lightning protection. This chapter introduces the reader how to design a receiver system, whose ground leads. It also describes the use of internal lightning protection, surge protection devices. The second part of this thesis examines the use and installation characteristics of the active elements, which may afford some extras to man. In the third practical part author compiled project of realization of wiring a house, which includes drawing circuits, devices and equipment into the house floor plan, electrometer housing scheme and also includes design drawing external lightning protection and its deployment. There are also necessary technical documentation with the economic evaluation of the created object.

Overcurrent protection relay testing using tester TZO3.
Vavreczky, Gábor ; Paar, Martin (referee) ; Toman, Petr (advisor)
The main task of this bachelor’s tesis is testing digital protection 7SA610 from Siemens. Purpose of the project is to take up with overcurrent functions of the protection, and realize it's testing through secondary tester TZO3. For this, the project grants theoretical foundations: deals with basic fault conditions in electrical networks, in detail describes the principle of individual types of overcurrent protections, grants informations about the used tester and about the used protection. In the final section of the thesis suggests applicable laboratory task in teaching at Department of Electrical Power Engineering, based on performed tests.

Problems of measurement and evaluation of transient resistance in electrical engineering
Štěpanovský, Libor ; Cipín, Radoslav (referee) ; Veselka, František (advisor)
The aim of the Bachelor Thesis is to introduce the revisions to electrical wirings and equipment, to get familiarized with the problems of transient resistance and with measurement of transient resistance in electrical engineering. The first part of the Thesis describes various types of revisions, the procedure to carry out revisions and the methodology that must be followed during the revision. The second part is dedicated to transient resistance. It mentions factors which influence the magnitude of transient resistance, methods used to determine the magnitude of transient resistance and a practical demonstration of a transient resistance measurement.

Radar Antenna Diagnostic Module
Pacner, Petr
Faults in the electrical wiring can cause fatal problems in particular application. Therefore various Fault Detection, Isolation and Recovery techniques have been developed, able to detect these faults. Such Defects may occure on a coaxial cable lines in radar systems between transmitter (receiver) and antenna. The aim of this paper is to present simulations of sequence time-domain reflectometry method. The results indicate suitability of this method for transmission lines terminated with radar antenna and capability of reliable soft faults detection (short and open circuit).
