Field windings made of MgB2 wires or tapes are considered for their potential to reduce volume, weight and cost of large offshore wind turbine generators. To gain experience of how to use this relatively new material in full-scale generators, tests of different winding methodologies and techniques a...

In this paper we present experimental and numerical studies of the electrohydrodynamic stretching of a sub-millimetre-sized salt water drop, immersed in oil with added non-ionic surfactant, and subjected to a suddenly applied electric field of magnitude approaching 1 kV/mm. By varying the drop size,...

Infrastructures such as road crossings, are often limiting the ampacity of a cable link due to poor thermal properties. In order to fully utilize the true loading capacity of the cable, thermal modelling with correct input parameters should be applied. In this work, a full scale artificial road cros...

Ved å bruke dobbel loop, så øker stivheten til omføringsloopen slik at egenfrekvensen øker og resonans med vinden unngås/reduseres. Dette gir igjen redusert utsving i omføringsloopen. Simuleringene viser at antall avstandsstykker har stor betydning for å ø...

This paper presents results from numerical calculations of water ingress in a wet designed subsea XLPE cable equipped with a two-layered outer sheath, and results from water tree ageing at different relative humidity (RH) levels in an XLPE cable core. The results from the water tree ageing show that...

Results are presented concerning the influence of an applied electric field on the coalescence of a water droplet with a much bigger water drop, both drops being immersed in a crude oil. This original study of electrocoalescence in crude oil was performed through high-speed optical observations, usi...
