  1. 1. Electromagnetic Interference in Distributed Outdoor Electrical Systems, with an Emphasis on Lightning Interaction with Electrified Railway Network

    Author : Nelson Theethayi; Rajeev Thottappillil; Farhad Rachidi; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Electrical engineering; Electromagnetic Compatibility EMC ; Lightning; Lightning Protection; Transmission Lines; Electromagnetic Wave Propagation; Underground Cables; Grounding; Electromagnetic Transients; Electromagnetic Interference; Shielding Effectiveness; Railway Systems; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : This thesis deals with the electromagnetic compatibility (EMC) problems of distributed electrical networks, especially that caused by lightning to electrified railway. Lightning transients were found to damage important devices that control train movements, causing traffic stoppage and delays. READ MORE

  3. 3. Feasibility of HVDC for city infeed

    Author : Paulo Fischer de Toledo; KTH; []
    Keywords : ;

    Abstract : It is well recognized that direct current and direct voltageoffer special advantages for both land and sea cable systems,both with regard to power transmission capability, losses, aswell as possible transmission length due to no capacitivecurrents. As cable systems were used very early in largecities, one of the first applications considered for HVDC wasto use it for city infeed and some schemes were also built. READ MORE

  4. 4. The Effect of Crosslinking on Morphology and Electrical Properties in LDPE Intended for Power Cables

    Author : Susanne Nilsson; Chalmers University of Technology; []
    Keywords : LDPE; morphology; electrical treeing; peroxide; crosslinking; XLPE; water treeing;

    Abstract : Crosslinked polyethylene (XLPE) is used as underground cable insulation due to its outstanding electrical properties and high temperature dimension stability. XLPE is often made by peroxide initiated crosslinking of low density polyethylene (LDPE). The introduction of unsaturations, i.e. READ MORE

  5. 5. Reliability analysis and maintenance scheduling considering operating conditions

    Author : Dhananjay Kumar; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Abstract : In reliability analysis failure times are often considered as the only factor that can explain the reliability characteristics of a system. This may be insufficient. Operating conditions and other factors (e.g. READ MORE
