Hybrid Resistive-Capacitive and Ion Drift Model for Solid Gas Dielectrics

Nils Lavesson [1], Charles Doiron [2],
[1] ABB Corporate Research, Västerås, Sweden
[2] ABB Corporate Research, Baden-Dättwil, Switzerland

INTRODUCTION: Many electrical insulation systems use a combination of gas and solid media. Typical examples considered here include the combination of solid epoxy insulation and SF6 in a gas insulated subsystem (GIS). To understand how such a system performs under DC voltages, accurate ...

Simulation of Novel Groundwater Lowering Technique using Arbitrary Lagrangian-Eulerian Method

Y. Jin, E. Holzbecher, and P. Oberdorfer
Applied Geology
Geoscience Centre
Georg-August-University Göttingen
Göttingen, Germany

A novel method for groundwater lowering, which can be applied at construction sites, for aquifer remediation measures or in open mining, is proposed. In contrast to conventional techniques, dewatering is achieved without water conveyance. In this paper the physical concept of the new ... En savoir plus
