Solving the problem of exploitation of transformers with corrosive sulfur by oil desulfurization using a strong inorganic base and organic solvent

Autor: Kolarski Dejan, Janković Jelena, Mihajlović Draginja, Kovačević Neda, Lukić Jelena

Publikováno v: Zbornik Radova: Elektrotehnički Institut "Nikola Tesla", Vol 31, Iss 31, Pp 113-123 (2021)

Most power transformer failures are associated with the presence of corrosive sulfur compounds in mineral insulating oil, of which dibenzyl disulfide (DBDS) is the best known and most widespread corrosive sulfur compound. The oil of failed transforme

Rešavanje problema eksploatacije transformatora sa korozivnim sumporom desulfurizacijom ulja primenom jake neorganske baze i organskog rastvarača

Autor: Kolarski, Dejan, Janković, Jelena, Mihajlović, Draginja, Kovačević, Neda, Lukić Jelena

Jedan od značajnih rizika havarije energetskih transformatorima je prisustvo korozivnih sumpornih jedinjenja u mineralnom izolacionom ulju od kojih je dibenzil-disulfid (DBDS) najpoznatije i najrasprostranjenije korozivno jedinjenje sumpora. Havarij

Karakterizacija izolacionih papira primenom FTIR-ATR spektroskopije

Autor: Planojević, Jelena, Lukić, Jelena, Vasović, Valentina, Mihajlović, Draginja, Janković, Jelena, Kovačević, Neda

Potreba za povećanjem produktivnosti i kapaciteta energetskih transformatora uslovila je proizvodnju izolacionih papira više termičke klase. U tu svrhu se primenjuju najrazličitije tehnike modifikacije čvrste izolacije koje omogućavaju povećan
