A Sample ARC Detector Panel
Pala, Lukáš ; Valenta, Jiří (referee) ; Kadlec, Radim (advisor)
In the introduction an electric arcs creation in low voltage networks is discussed, followed by evaluation of verification measurements with AFDD. A serial arc generator is designed in accordance with easy manipulation and low maintenance requirements. Technological solution for safe fault simulation is described similarly as particular function sections of demonstration panel. Schematic diagrams of power and electronic circuits are attached.

Methods of ignition spark gaps
Pekárek, Dominik ; Štěpánek, Jaroslav (referee) ; Krbal, Michal (advisor)
This thesis deals with methods of spark gap ignition. The thesis describes spark gap ignition by external electrode, by Rogowski electrode and by lasers. Advantages and disadvantages of these methods are also discussed. In the final part of the thesis there is described experiment with high voltage spark gap.

Surge in electrical networks and protection of electrical devices against surge
EFFENBERK, Kryštof
The bachelor thesis is focused to problems with surge. Different kinds of surge are distinguished in the introduction. Specifically it deals with the atmospheric surge and switching surge. Further on it describes surge waves and their propagation along lines of low voltage. The next section is focused on blueprints of signal generator. In a later section the author moves to the basic level of surge protection and surge protection devices. Last part of the bachelor thesis researches place, where we can plant surge protection devices. It also explains the behavior of the surge waves at interfaces of different impedances.
