Valuation of damage caused by a lightning strike to a house in the village of Šebetov
Šumberová, Petra ; Klimeš, Jan (referee) ; Šmahel, Milan (advisor)
The aim of this diploma thesis is to determine the amount of indemnity for damage caused by a lightning strike to a house in the village Šebetov. The thesis is dividend into theoretical and practical part. The theoretical part deals with the basic concepts, associated with the topic. Furthermore, the approach of valuation of assets and insurance. The practical part uses theoretical knowledge addresses a specific case. First, the location is described, house and insured event (natural event – flash). Following the calculation of the time value immediately before the insured event, further costs are quantified to repair the damage incurred and then is detected current value after repairs. At the end, there is comparison of the time price comparisons of costs incurred for repairs and evaluation of the agreed sum insured in the insurance contract.

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.

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.

Thunder detector (lightning indicator)
Trávníček, Tomáš ; Rampl, Ivan (referee) ; Chmelař, Milan (advisor)
The aim of this Bachelor’s thesis is to gain knowledge from the storm, it’s manifestations, detection through these speeches and then using this knowledge gained to design a simple indicator of thunderstorm’s (lightning), which will operate on the principle of counting flashes. The drafting of the principles and use of simple electronic component’s. The result of all this work is making a functional indicator of the sample.

Design of a new ion counter for the nature environment
Roubal, Šimon ; Szabó, Zoltán (referee) ; Roubal, Zdeněk (advisor)
Subject of this bachelors thesis is an realization of new control board for iontmeter that is developed at UTEE. Iontmeter must be capable of fully autonomous measure in outside contitions. That means it has to be able to run on batery for a long time and has to be to resist outside weather conditions. Measured data will be saved on an SD card and also sent using GSM network to the IoT server.

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.

Design of overvoltage protection for the object with explosive risk
Polášek, Roman ; Novotný, Jan (referee) ; Bátora, Branislav (advisor)
This master´s thesis deals with the designing process of surge protection for the object potentially explosive atmospheres and according to a set of standards ČEN EN 62305 and ČSN EN 60079. This work consists of four main parts. The first part deals with the theory of lightning and surges. Subsequently, in the second part is devoted to the theory of protection against these phenomena and proposals for external and internal lightning protection and surge. This chapter also deals with more demands on electrical installations in hazardous areas. The third part deals with the analysis of the risks to the subject paint and according to ČSN EN 62305-2 ed.2 and at the conclusion of the study is a proposal for external lightning protection and internal surge protection.
