Detail design documentation for the electrical installation Loxone of a passive house with PV system
Bolf, Marek ; Topolánek, David (referee) ; Bátora, Branislav (advisor)
The thesis deals with the design of high-current and low-current electrical wiring in a house, with emphasis on their connection to the intelligent control system Loxone. The thesis describes the house, the principle of designing lightning protection, the way of cabling, the options to control individual technologies by the Loxone system and the description of proprietary Loxone protocols and protocols through which Loxone system can communicate with other devices. In the practical part was prepared drawing documentation for the lightning conductor, cable routes, detailed connection of Loxone buses and components and high-current and low-current switchboard. Furthermore, the technical report and the budget of the electrical installation were prepared.

Proposition of new type of injection material with electrically conductive function
Uher, Vojtěch ; Černý, Vít (referee) ; Drochytka, Rostislav (advisor)
The bachelor thesis deals with the design of a new type of grouting material with electrically conductive function suitable for connecting cracks and gaps in building protection systems against lightning strikes and surges. The theoretical part summarizes the important knowledge about the grouting and grouting materials, introduces the current state of knowledge in the field of lightning and surge protection of buildings and also the preconditions of electrical conductivity of cement-based composite materials. In the practical part are summarized selected properties, which the electrically conductive grouting material should have and the relevant standards tests for experimental verification of selected properties are described. A wide range of primary and secondary fillers are studied and the most suitable ones are chosen to achieve a low electrical resistivity value. At the end of the thesis, there are recipes based on amassed knowledge and using secondary fillers to reduce the environmental impact of the developed materials during mass production. Reduced resistivity has been demonstrated in recipes using waste carbon and chopped carbon fibers, but has failed to fully meet standard requirements. The result of the work are new recipes and knowledge that can serve as a basis for further research.

Electrical installation in family house
Tesař, Jan ; Procházka, Petr (referee) ; Ondrejček, Vladimír (advisor)
This Bachelor Thesis is concerned with the design of the electrical installation of a family house. There are two main parts of the thesis – theoretical basis and the main design. In the theoretical part the reader is at first introduced to a powerline section, in which the electrical installation from the powergrid to a terminal equipment is described. Next part is about a low voltage wiring, where the commonly used types of wiring and devices are described. In the third part the reader can read about a lightning protection and its inner and outer parts. The main design consist of situational designs of devices and wiring in the house, switchboard designs, revision of the electrical protection and 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.
