Theory and practice of fault location on MV cable lines in E.ON distribution networks
Macků, Dominika ; Holub, Martin (referee) ; Orságová, Jaroslava (advisor)
This thesis gives an overview on the fault of high-voltage cable transmission lines in the distribution system of the E.ON company. The first part of this thesis introduces reader to the topic of cable transmission lines, types of commonly used cables and the most commonly occurring faults. In the second part of this thesis, the methods of locating faults in cable transmission lines by professional personnel are explained. The third part deals with the analysis of a group of chosen occurred faults. The final part focuses on the statistics of fault occurrence on South Moravian region from 1.1.2017 until 1.1.2019.

Study of rehabilitation of selected parts of the water network
Tauš, Miloslav ; Kučera,, Tomáš (referee) ; Raclavský, Jaroslav (advisor)
Within this thesis was carried out a reconnaissance of water distribution network of the city of Slavkov u Brna. The reconnaissance consists of: age analysis of piping materials; water losses evaluation; failure rate evaluation. Then was done a condition assessment of water supply network according to a chosen methodology. Using CARE-W LTP RSM software were projected a few technical-economic alternatives of rehabilitation of water network of the city of Slavkov u Brna. Then was prepared a project of rehabilitation of chosen section of water network. The work resulted in recommendations for the owner and operator of the water network of the city of Slavkov u Brna.

TECHNICAL ANALYSIS OF THE LIFE OF THE PIPE MATERIAL OF GREY CAST IRON
Kozelský, Jiří ; Kriš,, Jozef (referee) ; Škrobánková,, Hana (referee) ; Raclavský, Jaroslav (advisor)
The dissertation describes the technical analysis of the pipe material of gray cast iron, which is developed on the basis of historical documents and standards. The technical analysis is a methodology for determining the technical state and theoretical residual life of the pipe section made of cast iron, which is processed into a software application Kozel 1.0. The proposed methodology operates on the basis of multi-criteria decision making. For input the data methodologies are designed to monitor the operators of water supply networks. The output of the methodology is to determine the category of the technical condition of the pipe section and time stamp, minimum and maximum residual lifetime analysis pipeline segment. Outputs of the methodology are compared with the outputs of medium-term plans of Ostrava and Brno.

Rail Safety device applied in railroad station
BÁRTA, Jan
The aim of this bachelor thesis is to create a basic overview of station security equipment used in the Czech railway network. The bachelor thesis deals with the basic types, principles and control of security devices. It describes the external parts of the security device, such as locks, switches, bolts and lights, which are controlled and secured by many types of security devices and aids. This thesis presents the development of security devices and points out the sequence of evolutionary steps of the device. More space in this thesis is devoted to electromechanical equipment and operating procedures. Electromechanical equipment uses the same principles and procedures for building train paths, similarly to modern electronic interlocks. There are several aspects to the development of a security device. The main task is to eliminate the human error factor, further speed up construction and increase control over the position of train paths. Today's modern technologies help to do this. The thesis introduces the concept of failure rate and the basic division of the causes of failures. Due to external influences, failures cannot be fully avoided, but they can be recorded in more detail and prevented it by quality operation and maintenance. This is the main reason for creating this thesis, which can help new entrants to maintain security equipment with their training and education for their future careers, so that the railway remains the safest land transport.
