Surge in electrical networks and protection of electrical devices against surge
EFFENBERK, Kryštof
The bachelor thesis is focused to problems with surge. Different kinds of surge are distinguished in the introduction. Specifically it deals with the atmospheric surge and switching surge. Further on it describes surge waves and their propagation along lines of low voltage. The next section is focused on blueprints of signal generator. In a later section the author moves to the basic level of surge protection and surge protection devices. Last part of the bachelor thesis researches place, where we can plant surge protection devices. It also explains the behavior of the surge waves at interfaces of different impedances.

Design of Lightning Protection of Family House
Kovář, Zdeněk ; Bátora, Branislav (referee) ; Toman, Petr (advisor)
Bachelor´s thesis decribes the fundamental theory that is necessary for the proper design of the house from the damaging effects of lightning. The aim is to give a brief and comprehensive look into the issues. The first part of this thesis describes the emergence of lightning, adverse effects on protected and unprotected building and risk analysis. The second part presents the different types of protections. The following third part describes a brief overview of the history of standards and regulations and overview of standards currently valid in the Czech Republic. The last part of the thesis deals with the creation of my own proposal for lightning protection for the chosen fictitious family house.

Application of surge protection in LV networks
Brtnický, Pavel ; Šlezingr, Jan (referee) ; Bátora, Branislav (advisor)
The work include the issues about surge protection in low voltage networks. The first part give a theoretical analysis of the surge protection, where is described own creation and basic division. The second part give a inner and outer protections, where is characterized, what protections contain and methods, with which to design protection. In the third part is few words about computer softwares, which supports dimensioning and design protections. The second half of the work give a specific design of protections for fire station, first there are determinated risks for building without surge protection and after for building under surge protection, design of outer protection together with verification and design of inner protection.

Fast Transient Phenomena in High Voltage
Vala, Martin ; Dohnal, Petr (referee) ; Krbal, Michal (advisor)
This work deals with research and description of the fast transients in high voltage technics. First part deals with division of fast transients and description of an impulse wave properties. Second part is focused on atmospheric overvoltage description and on direct and indirect lightning surge protection methods. Next, there are described the main characteristics and division of the surge protection devices in the work. In the next part, there are introduced some sort of high voltage generators, used for meassurement of impulse wave in a transmission line. In the last part there is stated an analysis of practical measurement of impulse weaves and surge arresters by using a Marx generator.

Design of power and data network of office building
Vančura, Jan ; Novotný, Jan (referee) ; Bátora, Branislav (advisor)
This thesis describes a design of a power and data network. The aim is to create a wiring project of an office building. The introduction of this paper describes, which requirements should have a project documentation and which software is used for designing. The third chapter deals with a description of parameters, which are used for lighting design. The fourth chapter describes power distribution, the types of power distribution (light, socket) and how they are being correctly designed. The fifth chapter analyses data distribution (EZS, EPS, TEL, …). There are designed surge protection and protection for the object in the last part of this thesis. The practical part focuses on creating a drawing documentation, which contains design of power and data network. All project documentation is further discussed in the technical report.

Application of overvoltage protection in LV networks
Knebl, Jan ; Novotný, Jan (referee) ; Bátora, Branislav (advisor)
This paper describes the design of surge protection for objects of civil construction. The aim of this paper is to acquaint the reader with the problems of this region, which is nowadays especially for houses neglected. The introductory part of the thesis is focused on the theoretical analysis of the problem and become familiar with the standards in force, without which a person moving in this field certainly can not do. In the first major section is a repartition surge in general terms. In the second chapter, a repartition of surge protection on the inside and outside and a description of the individual components of these protections. The third chapter is made complete design protection for the school building, the first step is an analysis of the risks to unprotected building, then the protected and ultimately design of internal and external surge protection. In the last chapter, a check is made of the risk analysis using DEHN Support.

The design of the lightning protection for the house
Tesař, Luděk ; Bátora, Branislav (referee) ; Toman, Petr (advisor)
This work describes the design rules for the lightning protection of civic construction. The aim of this work is to provide a comprehensive view of the basic design rules for the lightning protection. The actual design is preceded by the detailed introduction to the relatively large problems in this sphere. The introductory part is focused on the approach of technical standards and legislative requirements. In the second chapter the thesis deals with lightning in general and lightning current and its parameters. The following chapter focuses on the effects of lightning current, indicating the damage caused by lightning strikes to the building or its surroundings. Then the thesis deals with analysis and risk management. The next chapter describes and explains the system of external and internal lightning protection. The last part is devoted to a specific design of the lightning protection for the chosen house.

The desingn of the lighting protection for civil buildings
Šebesta, Ondřej ; Bátora, Branislav (referee) ; Toman, Petr (advisor)
This thesis focuses on the issue of lightning protection and goes along with ČSN EN 62 305 norms. First part goes into effects of lightning on objects and engineering networks in theory. Second part familiarizes external lightning protection and possibilities of its realization. The issues of internal protection against lightning and surge protection are analysed afterwards. Second half familiarizes protected family house and the risks are calculated for this house. External protection is designed and verified by protective angle and rolling sphere methods. Last part of this thesis focuses on internal surge protection and individual levels of surge protection are designed.

Planning and design electrical protection in the house wiring
Chromík, Aleš ; Mastný, Petr (referee) ; Bátora, Branislav (advisor)
The work includes familiarization with the problems of protection from injuries by electric current that includes individual protections and their use. In the work is also included effect of electric current on humans. Another point is the familiarization of protection against external and internal atmospheric surge in house wiring. Project risk analysis, against injuries to living beings by lightning strike, is calculated for the protection of atmospheric surge. The main point of this work deals with the procedure of design process of house wiring protections for given object. The project includes technical drawing, which contains how to design power and data distribution systems and switchgears, as well as the drafting of lightning system which accuracy is verified by the methods of protective angle and the ball rolling. Design and location of the right types of surge protection arresters is selected for a given objects. All project documentation is discussed in the technical report, which refers to existing standards.
