  2. 1. Voltage Stabilisers for XLPE Cable Insulation

    Author : Villgot Englund; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polyethylene; insulation; electrical treeing; degradation; cable; stabilisers; XLPE;

    Abstract : The demand for energy in the Western world has istorically increased steadily and a steady increase is forecasted for the next decades. This steady increase together with the huge merging markets in India and China are setting new standards for the energy transmission. READ MORE

  4. 2. The Physical Axon : Modeling, Simulation and Electrode Evaluation

    Author : Malcolm Latorre; Karin Wårdell; Göran Salerud; Ulrich Hofmann; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Electrodes are used in medicine for detection of biological signals and for stimulating tissue, e.g. in deep brain stimulation (DBS). For both applications, an understanding of the functioning of the electrode, and its interface and interaction with the target tissue involved is necessary. READ MORE

  5. 3. Measuring degradation in cable insulation material under realistic operation conditions

    Author : Douglas Jutsell Nilsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : One of the challenges in laboratory investigation of degradation and ageing of HVDC cable insulation is related to securing, or in other words, imitating the real service environment of the material specimens. So far, the published data refer to experiments conducted in thermo-oxidative conditions, which is not the case during normal cable operation. READ MORE

  6. 4. Automation of underwater operations on wave energy converters using remotely operated vehicles

    Author : Flore Remouit; Jens Engström; Antonio Pascoal; Uppsala universitet; []
