  7. 35. On the estrablishment of effective condition monitoring parameters for copper corrosion problems in mineral oil-filled electrical transformers

    Författare :Ramsey Jadim; Mirka Kans; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; condition monitoring parameters; corrosion problems; sulfur deposits; corrosion reaction mechanisms; transformer failures; CBM.; Maskinteknik; Mechanical Engineering;

    Sammanfattning : The power transformer is a critical equipment in which the protection process is essential for modern societies where continuous electric power supplies are required. Copper corrosion problems due to the formation of sulfur deposits on the copper windings of mineral oil-filled power transformers are considered a major issue that can lead to sudden failures, and in some cases, to costly fire and explosion accidents in the power plants.
