The moisture effect on properties of insulating materials exposed to thermal and electrical stress
Janošek, Michal ; Frk, Martin (referee) ; Rozsívalová, Zdenka (advisor)
The diploma thesis with experimental verification influence moisture of the dielectric properties of non-aged and thermally, electric and multistress aged slot insulation Isonom NMN. Above all both components of the complex permittivity are examined in dependence on frequency during the thermal, electric and multistress ageing. Practical part is specialized on design, realization and examination of workplace multistress ageing.
Effects of multistress ageing on the insulating materials properties
Kučera, Miroslav ; Frk, Martin (referee) ; Rozsívalová, Zdenka (advisor)
This bachelor´s thesis treat of influence of relative moisture environment and electrical and combined stress on the dielectric properties of the slotted isolation ISONOM NMN. Under examination are above all both components of the complex permittivity in dependencies on frequency and in dependencies on temperature with method dielectric relaxation spectroscopy.
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.
