Local Electric Field in Mass-Impregnated HVDC Cables
Håkonseth, Gunnar; Ildstad, Erling; Furuheim, Knut Magne (Journal article; Peer reviewed, 2017)Detailed knowledge of the electric field in the insulation of mass-impregnated HVDC cables is important in order to understand their breakdown mechanisms and to improve their design. When calculating the local electric ... -
Synergy Effects between Polyethylene and high Density Papers in Gas Barrier Materials - a Morphological Study
Furuheim, Knut Magne (Dr. ingeniøravhandling, 0809-103X; 2002:39, Doctoral thesis, 2002)This work has its origin in efforts to optimise the barrier properties of packaging materials in which polyethylene extrusion coated high-density paper constitute the oxygen barrier. Examples of applications where this ... -
Transient Electric Field Distribution Estimates for Layered Paper-Oil High Voltage Direct Current Insulation: Effects of Slow Polarization and Applicability of Dielectric Response Theory
Håkonseth, Gunnar (Doctoral theses at NTNU, 2020:342, Doctoral thesis, 2020)The aim of this work is to contribute to an increased capacity of mass-impregnated, high voltage direct current (HVDC) cables. This has been done by providing a better understanding of the transient electric field distribution ...
