20.500.12556/RUL-137574 Analiza in interpretacija raztopljenih plinov v transformatorskem olju Analysis and interpretation of dissolved gases in transformer oil Tekom obratovanja transformatorja je pomembno preverjati stanje transformatorja. V praksi to pomeni, odvzemanje vzorcev olja iz transformatorja in analiziranje v certificiranih laboratorijih. V diplomski nalogi smo si ogledali kako se tvorijo plini v transformatorju, katere vrste plinov se tvorijo tekom različnih vrst okvar, merjenje koncentracije plinov tekom obratovanja transformatorja, odvzem vzorcev olja in interpretacija meritev z Duvalovim trikotnikom in Duvalovim pentagonom. Na podlagi oljnih analiz, ki smo jih izvedli v Kolektor Etri, smo preverili, ali obstajajo odstopanja v koncentraciji plinov na podlagi različnih transformatorskih zasnov po končanih tovarniških meritvah. During transformer operation it is important to monitor condition of the transformer. In practice, this means taking oil samples from the transformer and analyzing them in certified laboratories. In this diploma thesis the following analysis has been done: the formation of gases in a transformer, which types of gases are generated during different types of faults, measurements of gas concertation during operation of the transformer, taking of oil samples and interpreting measurements with the Duval triangle and the Duval pentagon. Based on oil analyzes performed at Kolektor Etra, we checked whether there were deviations in the gas concentration based on various transformer designs after the factory measurements were completed. transformator DGA tvorjenje plinov olje Duvalov trikotnik Duvalov pentagon. transformer DGA gas formation oil Duval triangle Duval pentagon. true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2022-06-22 11:10:00 2022-06-22 11:10:02 2022-09-15 04:15:24 0000-00-00 00:00:00 2022 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 60975 112509187 Kovacic_Ziga_-_Analiza_in_interpretacija_raztopljenih_plinov_v_transformatorskem_olju.pdf Kovacic_Ziga_-_Analiza_in_interpretacija_raztopljenih_plinov_v_transformatorskem_olju.pdf 1 ADDC65545F0DE13CBC1A701CC39A2834 f627a6ca3eba077976af6e831ebbe61d22d8bbe50d10731e3b33038c993f7ba5 e8cf8b2e-f20a-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157575 Fakulteta za elektrotehniko 0 0 0
