Proposal of electrical equipment for soaking and drying cores for making castings
Čermák, Jiří ; Hájek, Vítězslav (referee) ; Veselka, František (advisor)
This diploma thesis deals with proposal of electrical equipment for soaking and drying cores for making castings at foundry in a Great Britain. It brings look at system of technical norms ČSN and it compares it with british system of technical norms British standards. The second part of this thesis contains detailed proposal of this equipment, including specification of control system, specification of power supply cables and control cables and particular technological units. The whole project documentation is enclosed as an inseparable attachment of this diploma thesis.

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.
