Generation of Voltage Wave by Impulse Generator
Poloni, Miroslav ; Krbal, Michal (referee) ; Pelikán, Luděk (advisor)
The presented bachelor thesis deals with the problems and functions of impulse voltage generators. The theoretical part describes the functions and various connections of the impulse generator, types of impulse voltage, tests and test procedures. In the practical part of the work, theoretical knowledge in the form of simulations was verified. The simulations were performed in the LTspice program from Linear Technology, where the impulse generator model was made. Simulations were then performed on the given model of the shock generator, from simpler ones such as the dependence of the size of the load capacity to the inductance connected in parallel. The results of all simulations should bring benefits and ease in real shock generator tests
Accelerated aging of cross-linked polyethylene cable insulation
Poloni, Miroslav ; Krbal, Michal (referee) ; Pelikán, Luděk (advisor)
The present diploma thesis deals with the issue of accelerated ageing of insulation material of high voltage cables. As part of this work, two accelerated aging experiments were done. The aim of these tests is to achieve accelerated degradation of the insulation material and possibly predict the lifetime of the cables in service.
