Mathematical transformation in dielectric relaxation spectroscopy
Brida, Marek ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
This labor treats the problem of dielectric relaxation spectroscopy in time domain, measurement of the absorption characteristics and their conversion to the frequency domain by creating a frequency depends of loss factor. Paper reports an overview of the most common mathematical transformation and approximation, which are used for this conversion and they also compare some of them. Mathematical methods used in this paper are Fourier transformation and Hamon approximation. Measured dielectric insulation is slot insulation type Isonom NKN 2039 and Isonom NMN 0967.
Properties diagnostic of slot insulations by means of DC electrical method
Brida, Marek ; Frk, Martin (referee) ; Rozsívalová, Zdenka (advisor)
This labor treats of ageing process problems in slot insulations their diagnostic with usage of one way measuring methods. Experiment was pointed on measuring and evaluation absorption characteristic of electrical and thermal stressed slot insulations type of Isonom NKN 2039.
