An effect of natural phenomena on electrical devices
Müller, Michal ; Aubrecht, Vladimír (referee) ; Bušov, Bohuslav (advisor)
The Thesis deals with the impact of natural effects on electrical equipment. It describes the various natural effects and shows how it impacts, what it impacts on and what the source of its impact is. The main point of this Thesis is the issue of atmospheric charge (storm and lightning) and the issue of coronal mass ejection (CME). The Thesis shows causally consequences string of geomagnetical field disturbances and resultant power system impacts. There are mentioned historic storm events and power system impacts and description of events in Hydro-Quebec – the most important event. Of this species. At the end there are shows possible way of mitigation power system impacts.

Problems of measurement and evaluation of switching loop impedance
Švéda, Miroslav ; Bárta, Jan (referee) ; Veselka, František (advisor)
This work is applied to questions about impedance of tripping loop. It deals with problems of measuring impedance of tripping loop, different measurement, procedures and accuracy of these measurements. Further, the work deals with the subsequent evaluation of the measuring impedance of tripping loop and writing of the measurement results. The work also focuses on the impedance of tripping loop in terms of the operation of the protective elements of the electrification system. Finally, the practical measurement of the impedance of tripping loop in real electrical circuits is performed as part of the work.

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.
