Multistress ageing analysis of the electroinsulating materials
Jeřábek, Michal ; Frk, Martin (referee) ; Rozsívalová, Zdenka (advisor)
This diploma thesis deals with not-aged and thermally, electric and multistress aged slotted isolations dielectric properities experimental probing. Dutiny experiment is watched influence moisture on dielectric properties insulating materiále ISONOMŽNMN. Especially both two permitivity complex components are surveyed, in dependence on the frequency and the temperature changes during thermal, electric and multistress ageing. These characteristics are viewed in light of application the isolation in practice.

Study of electrical stress of slot insulations
Jabůrek, Ladislav ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
This bachelor works deals with electrical effort problems of dielectric materials. The general aim is study of impact alternating electric field of great effort on slot insulation Nomex-Kapton-Nomex. Measurement of loss is realised by dielectric relaxation spectroscopy in frequency domain method. The another aim is apprise of electrical aeging, its causes and incidence on materials. Works deals below dielectric relaxation spectroscopy in time domain and frequency domain, fundamental effect in dielectric and measurement values coherent with electrical aeging.

Analysis of multistress ageing on dielectric spectras of materials
Kučera, Miroslav ; Frk, Martin (referee) ; Rozsívalová, Zdenka (advisor)
Diploma thesis treat of effect of thermal, electrical and combined (thermal electrical) stress on electrical characteristics of insulation material ISONOM NMN which is used as a slot insulation in electric motors. To monitor the stress is used the method of dielectric relaxation spectroscopy. Under examinations are the resultant dielectric spectra which constitute the frequency dependencies of components of complex permitivity. Compared are the effects of particular stresses on dielectric spectra of surveyed insulative material.
