Abstract:Magistrsko delo obravnava delne praznitve z njihovimi specifičnimi lastnostmi v različnih dielektrikih. Pri predstavitvi dielektrikov je poudarek na umetnih polimernih materialih. Prikazan je nazoren opis pojava delnih praznitev v dielektrikih s podano fizikalno sliko. Predstavljene so metode, ki se uporabljajo za ocenjevanje delnih praznitev in obsegajo električne, neelektrične in statistične metode. Poseben poudarek je namenjen predstavitvi in uporabi Weibullove verjetnostne porazdelitve za ocenjevanje vrednosti delnih praznitev. Za posamezne primere izmerjenih delnih praznitev v laboratoriju je prikazan način analize delnih praznitev z uporabo Weibullove porazdelitve. Podani so rezultati analize za posamezne primere delnih praznitev in potrjena je uporabnost Weibullove analize za ocenjevanje delnih praznitev.

Title:RECOGNITION OF PARTIAL DISCHARGE IN DIELECTRICS BY THE HELP OF WEIBULL DISTRIBUTION
Abstract:The master thesis deals the partial discharges and their specific property in different dielectrics. The main emphasis at dielectrics presentation is made on synthetic polymer materials. The evident description of partial discharge phenomenon in dielectrics with physical count is presented. The methods for estimation of partial discharge, which include electrical, nonelectrical and statistical methods are described. For presentation and use of Weibull probability distribution for partial discharge estimation a special emphasis is intended. For individual examples of measure of partial discharge in laboratory the method of analysis with the use of Weibull distribution is represented. The results of analyses for individual example of partial discharge are given. Applicability of Weibull distribution for estimation of partial discharge phenomenon is confirmed.
Keywords:dielectrics, partial discharge, electric field, Weibull distribution, electrical network, insulation elements
