Protective measure - automatic disconnection of suply
Leitner, David ; Vaněk, Jaromír (referee) ; Valenta, Jiří (advisor)
The aim of this thesis is to explain the principle of automatic disconnection of supply, which is one of the basic protective measures for security assurance in electric installations of low voltage according to the new issue of Czech Technical Standard (ČSN 33 2000-4-41 ed. 2). Furthermore, the relevant clauses of the Czech Technical Standard in the new and previous issues are compared, with focus on the problem of automatic disconnection of supply in basic types of distribution networks. In agreement with theoretical conclusions, a project of electric energy supply system is proposed in the practical part of the thesis. Special attention is paid to showing the methods of modeling and verification of conditions for automatic disconnection of supply, with using control calculations in the SICHR program. Finally, the fulfillment of the conditions for automatic disconnection of supply is verified by revising the electrical supply system.

Problems of measurement and evaluation of transient resistance in electrical engineering
Štěpanovský, Libor ; Cipín, Radoslav (referee) ; Veselka, František (advisor)
The aim of the Bachelor Thesis is to introduce the revisions to electrical wirings and equipment, to get familiarized with the problems of transient resistance and with measurement of transient resistance in electrical engineering. The first part of the Thesis describes various types of revisions, the procedure to carry out revisions and the methodology that must be followed during the revision. The second part is dedicated to transient resistance. It mentions factors which influence the magnitude of transient resistance, methods used to determine the magnitude of transient resistance and a practical demonstration of a transient resistance measurement.
