ANALIZA ELEKTRIČNE IZOLACIJE STARANIH KABLOV Z RENTGENSKO FLUOROSCENČNO SPEKTROMETRIJO
Povzetek
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. S pomočjo fizikalnih lastnosti in merilnih rezultatov pa lahko oblikujemo tudi matematične modele, ki opisujejo staranje materialov ob prisotnosti posameznih vplivov. Cilj 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. S pomočjo standardnega testa indenter modula lahko določimo referenčne točke, na podlagi katerih se izvede rentgenska spektralna analiza. Z vzorčenjem teh točk različno degradiranih kablov pa se vzpostavimo merila sprejemljivosti kabelske izolacije.
