    • Control of Water Tree Length and Density in Cable Insulation Polyethylenes 

      Hampton, Nigel; Ciuprina, Florin; Teissedre, Gisele; Fillippini, Jean; Smedberg, Annika; Campus, Alfred (Georgia Institute of Technology, 2006-06)
      The goal of this paper is to study the influence of the chemical crosslinking of polyethylene on the water tree initiation and propagation in polymer insulation. For this, the water tree resistances of crosslinked and ...
    • Effect of Size on Electrical Performance 

      Smedberg, Annika; Wald, D.; Hampton, Nigel (Georgia Institute of Technology, 2006-06)
      The electrical breakdown performance, either unaged or after ageing (laboratory or service), is often used as the basis for qualification of a device, design or material. Many of the features that affect these performance ...
    • Improved Understanding of Extruded MV Cable Performance Through the Modification of Existing Approval Protocols 

      Hampton, Nigel; Hartlein, Rick (Georgia Institute of Technology, 2007-06)
      Cable users and manufacturers have an increasing wish to gain a deeper understanding of cable performance, beyond the knowledge that it simply complies with the minimum performance level defined within a standard. Although ...
    • Long-Life XLPE Insulated Power Cable 

      Hampton, Nigel; Hartlein, Rick; Lennartsson, Hakan; Orton, Harry; Ramachandran, Ram (Georgia Institute of Technology, 2007-06)
      Crosslinked polyethylene (XLPE) has become the globally preferred insulation for power cables, both for distribution and transmission system applications. This insulation system provides cost efficiency in operation and ...
    • On Distribution Asset Management: Development of Replacement Strategies 

      Hampton, Nigel; Hartlein, Rick; Begović, Miroslav; Perkel, Josh (Georgia Institute of Technology, 2007-07)
      The components of electricity networks are ageing. It is expected that within a horizon of 15 years, the performance will deteriorate significantly, while the costs for operating the networks will increase enormously. The ...
    • Practical Issues Regarding the Use of Dielectric Measurements to Diagnose the Service Health of MV Cables 

      Hampton, Nigel; Hartlein, Rick; Hernandez, Jean; Harley, Ronald (Georgia Institute of Technology, 2007-06)
      During the last decade, Very Low Frequency (VLF) testing for extruded distribution cables has gained interest among the North American utilities. The increasing interest is evidenced by recent research publications and ...
    • The Role of Degassing in XLPE Power Cable Manufacture 

      Andrews, Tim; Hampton, Nigel; Smedberg, Annika; Wald, D.; Waschk, V.; Weissenberg, W. (Georgia Institute of Technology, 2006-11)
      This article focuses on a range of elements critical to this process; form the fundamental chemistry, through computational and measurement techniques to the solutions that are in use today. Degassing contributes greatly ...
    • Some Considerations on the Selection of Optimum Location, Timing, and Technique, for Diagnostic Tests 

      Hartlein, R. A.; Hampton, R. N.; Perkel, Josh (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2008-07)
      The ageing of the electrical infrastructure is a growing concern for utilities, regulators and customers; and there is no doubt that addressing this problem will become an ever more important priority. Any solution will ...
    • A Survey on Communication Networks for Electric System Automation
