  • Effect of barrier and its shape over the breakdown voltage of oil gaps 
    Ediriweera, WEPS; Jayarathna, KLIMPB; Samarasinghe, R; Lucas, JR [Conference-Full-text]
    This paper studies the use of insulating barriers on the breakdown voltage of oil gaps upon two type of coconut oils under AC voltage. A point plane electrode arrangement connected to a AC transformer is used to find ...
  • Influence of water and powder contaminants on dielectric strength of transformer oil 
    Abeyrathna, MSM; Karunaratne, MMLK; Kahingala, KPV; Samarasinghe, R; Lucas, JR [Conference-Full-text]
    Transformer failure statistics reveal that most of the transformer failures are due to insulation failures, where a considerable fraction of that percentage is caused by oil contamination. In this paper, the influence of ...
