    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Svante Karlsson; [2016]
    Keywords : ;

    Abstract : Power transformers are one of the most expensive and vital components in the power system. A sudden failure could be a very costly process for both the transformer owner and the society. READ MORE

  6. 5. Locating Faults on Energized Airfield Lighting Power Cables

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Dennis Honkanen; Simon Anderjon; [2016]
    Keywords : Fault Location; State of Health; Airfield; Lighting; LED; Fault; Series Circuit; Technology and Engineering;

    Abstract : The purpose of this study is to investigate the feasibility of both online and offline fault location and state of health technologies for airport series circuits used to provide power to light fixtures on the runway. In current series circuits, only some ground faults can be detected and no automated fault location or state of health features are available. READ MORE
