  5. 4. Modeling and OpenFOAM simulation of streamers in transformer oil

    Master-uppsats, Institutionen för fysik, kemi och biologi; Tekniska högskolan

    Författare :Jonathan Fors; [2012]
    Nyckelord :Computational Physics; High voltage; OpenFOAM; Streamer; Electric insulation; Electrodynamics; Finite Volume Method; Beräkningsfysik; Högspänningsteknik; OpenFOAM; Streamer; Elektrisk isolation; Elektrodynamik; Finita volymsmetoden;

    Sammanfattning : Electric breakdown in power transformers is preceded by pre-breakdown events such as streamers. The understanding of these phenomena is important in order to optimize liquid insulation systems. Earlier works have derived a model that describes streamers in transformer oil and utilized a finite element method to produce numerical solutions. LÄS MER
