Diagnostics of electroinsulating liquids properties
Makówka, Tomasz ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
The diploma thesis deals with the liquid insulators, their properties and their use in the electrical industry. The general aim is to study the physical essence of the dynamic viscosity, the electric conductivity and the diagnostic methods for monitoring these variables. The experimental part contains measuring the dynamic viscosity and the electric conductivity of the mineral transformer oils ESTO BNX, RENOLIN ELTEC and the biodegradable oil MIDEL 7131 during the degradation. The Walden rule is applied on measured results.
Sensors for non-destructive testing of the structural size of products
Makówka, Tomasz ; Murina, Milan (referee) ; Rez, Jiří (advisor)
The bachelor’s thesis is aimed at use of sensors for non-destructive testing of the structural size of products. More specifically, it is ingaged in magnetic poin-pole method and magnetization method for point-pole creation. The thesis contains design of experimental unit for point-pole method test on concrete material sample and amplifier for Halls probes implementation.
