Analysis of the technical designs of lightning protection for a commercial building with PV power plant
Paclík, Patrik ; Bátora, Branislav (referee) ; Ptáček, Michal (advisor)
The main objective of the thesis is the issue of lightning and surge protection and demonstration of its practical application at the level of a fictitious object. In the context of this, a search of the currently valid standards and legislation is carried out and a basic list of requirements for the creation of related project documentation is given a key complement of the thesis is the synthesis of lightning and surge protection with the protection of photovoltaic panels located on the roof structure of the building, where the issue of possible damage after lightning strike is addressed and the risks with external and internal protection are analysed. The thesis also includes an evaluation of possible collision in the application of lighting protection and photovoltaic panels, as well as the prevention of the spread of a possible fire from the roof to the object. Three different technical designs of external lightning protection are compared in terms of aesthetics, financial costs and practicality.

Design of lightning protection system for a multifunctional building
Drašnar, Antonín ; Bátora, Branislav (referee) ; Ptáček, Michal (advisor)
This final thesis describes the essentials required for the correct process of protecting objects against the destructive effects of lightning current. The focus of the practical part compares selected software tools that facilitates both the risk analysis process of possible damage caused by a lightning strike and enables the finding of adequate protection of the assessed object. The comparison of the software itself is made from the point of view of their availability, clarity and especially also from the point of view of the provided functionalities. The functionalities and options of each software are purposefully demonstrated on a defined complex building, for the implementation of two designs of the lightning protection system, specifically in the version with a distant lightning protection system and using the method of equipotential bonding. Both applied lightning protection are then compared in more detail in terms of technical and economic demands.

Design of lightning protection system for a historical building
Kytka, Jakub ; Janík, Daniel (referee) ; Bátora, Branislav (advisor)
The bachelor thesis deals with the problem of protection against atmospheric overvoltage for a historical building. The historical object is a dilapidated castle, whose investor will try to renovate or rebuild the castle in the future. The aim of the bachelor thesis is to introduce the issue and then to create project documentation for the implementation of the lightning protection system. The first theoretical part of the thesis is devoted to the basic introduction to surge protection, theoretical analysis and research of standards on the issue of internal and external surge protection. The second theoretical part is devoted to the issue of risk management and its analysis according to the applicable standards, including the determination of the risk of the object under consideration. In the first practical part, drawings of the roof plan and front/rear and side views were created. In the second practical part, a lightning protection design was created for the object. In the third practical part, a schematic for the surge protection design, a lightning protection budget and a technical report were created.

Numerical Analysis of the Lightning on Small Aircraft
Krutílek, David
This paper deals with numerical analysis of lightning stroke effects on aircraft. Computations are implemented by the use of the time-domain solver (FIT). Attention is turned to a simple model of a composite nose part of the airplane EV-55. The analysis of the model itself is performed for two fundamentally different basic conceptions of a possible protection against direct effects of lightning.

Indicator of Thunderstorm
Studený, Pavel ; Sekora, Jiří (referee) ; Chmelař, Milan (advisor)
The aim of this Bachelor thesis is a theoretical analysis of thunderstorms, lightning and their detection. The theoretical description then gradually moving towards designing their own detector. The detector will operate so that when a lightning activity captures pulses which generate lightning. Lightning will register using the attached counter. After the storm could be due to information from the counters to evaluate how strong the storm was.

Influence of hazardous EM fields on large objects
Klučka, Jaroslav ; Kovács, Peter (referee) ; Řezníček, Zdeněk (advisor)
This bachelor thesis deals with simulation of influences of electromagnetic field on an aircraft via computer program PAM-CEM. The aim of the simulation is verification of conditions for placing equipment and cables in chosen places. There were chosen two outer interfering electromagnetic fields: High Intensity Radiated Fields HIRF and a lightning bolt. During the simulation of HIRF, the plane was radiated by outer electromagnetic field. The decomposition of inner electromagnetic field was monitored during the exposure. Then, the electrical intensity was measured in three places, where the location of susceptible electronical devices was predicted. During the simulation of lightning bolt only indirect effects were taken into consideration. Current impulse was implemented into the skin of the aircraft and the decomposition of surface current was monitored.

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.

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.

Energy-efficient guest house in the city of Lednice
Joch, Tomáš ; Uher, Pavel (referee) ; Rubinová, Olga (advisor)
My Masters project is titled Energy-efficient guest house in the city of Lednice. The assignment is to design a building, which meets contemporary standards of energy efficiency. There are three parts of the project. The first part consists of designing the structure of the building. The building is L-shaped with pitched roof, single-storey with attic. There is a pool with sauna, restaurant with kitchen and main hall with entrance and reception on the ground floor. At the attic there are twenty two dwelling units for guests, common room and staff facilities. The main entrance is oriented towards east. The building is masonry system from sand-lime blocks with prefabricated reinforced concrete floor slabs and roof is made of timber roof truss. The building facade is insulated by ETICS. In the second part, there are designed HVAC, lightning and shading, rainwater usage and photovoltaic power station. In the third, there is a calculation of energy need for heating and cooling using monthly balance mehtod. The project is designed with support of AutoCAD, Revit and DEKsoftT softwares.
