Abstract:Namen magistrskega dela je celovit pregled obstoječih metod za analizo kablov oziroma kabelske izolacije. Delo zajema pregled električnih, mehanskih in kemijskih lastnosti ter merilnih metod za določanje njihovih parametrov. Analize temeljijo na fizikalnih osnovah, s pomočjo katerih lahko določamo stanje kabelske izolacije. Za lažjo analizo je treba temeljito poznati materiale, njihove lastnosti in sestavo. S pomočjo fizikalnih lastnosti in merilnih rezultatov pa lahko oblikujemo tudi matematične modele, ki opisujejo staranje materialov ob prisotnosti posameznih vplivov. Cilj dela je zasnova podlage za oblikovanje merilne metode z rentgensko spektralno analizo. Metodologija temelji na predpostavki, da se s staranjem materiala na površju zmanjšuje oziroma povečuje prisotnost posameznih elementov. Tako lahko s pomočjo standardnega testa indenter modula določamo referenčne točke, na katerih se izvede rentgenska spektralna analiza. Z vzorčenjem teh točk različno degradiranih kablov pa lahko vzpostavimo merila sprejemljivosti kabelske izolacije.

Title:Review of existing methods for assessing the lifespan of electrical insulation and analysis of cables using X-ray fluorescence spectrometry
Abstract:The purpose of the master's thesis is to provide a comprehensive overview of existing methods for the analysis of cable insulation. The work encompasses a review of the electrical, mechanical, and chemical properties, as well as measurement methods for determining those parameters. Analyses are based on physical principles that allow us to assess the condition of cable insulation. Thorough knowledge of materials, their properties, and composition is essential for easier analysis. Using the physical properties and measurement results, mathematical models can be formulated to describe the aging of individual materials in the presence of specific influences. The goal of the thesis is to establish the foundation for the development of a measurement method using X-ray spectral analysis. The methodology assumes that the presence of specific elements decreases or increases on the material's surface as it ages. By using a standard indenter modulus test, we can determine reference points for X-ray spectral analysis. Sampling these points on differently degraded cables enables the establishment of criteria for acceptable cable insulation.
Keywords:cable aging, polymer electrical insulation, x-ray fluorescence spectrometry, preventively maintenance
