  • Condition monitoring system for outdoor insulators 
    Karunarathna, IMAM; Karunathilaka, KLT; Wanasinghe, WMHM; Sampath, GKL; Lucas, JR; Samarasinghe, R [Conference-Full-text]
    High Voltage insulators are vital components in transmission and distribution systems in a power network. Most of the insulators are used in open air applications where they are subjected to different environmental ...
  • 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 ...
  • An improved wide frequency model for VFTO of power transformers using transfer functions 
    Jayarathna, KLIMPB; Ediriweera, WEPS; Samarasinghe, R.; Lucas, JR [Conference-Full-text]
    An accurate understanding of power transformer high frequency behavior is very important to assess the impacts on power system due to transient over-voltage conditions. An improved method of modeling power transformer ...
