Water Treeing in XLPE Insulation at a Combined DC and High Frequency AC Stress

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1038439

For many subsea HVDC cable systems, the DC current is transmitted through the HV cable in a voltage source converter (VSC) - HVDC scheme. Modulated upon the DC voltage are harmonics, which originate from the switching feature of the VSC stations. The main purpose of this paper is to examine the effe...

Influence of DC Stress Superimposed with High Frequency AC on Water Tree Growth in XLPE Insulation

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1047531

Power electronics used for HVDC converters will stress cable insulation with a DC voltage with superimposed transients. The effect these transients have on the performance of the polymeric cable insulation is yet not clear. The main purpose of this work has been to investigate the effect of such tra...

Design of a High Voltage Penetrator for High Pressure and Temperature Laboratory Testing

https://www.sintef.no/publikasjoner/publikasjon/?pubid=SINTEF+S21114

High voltage apparatus and reliable power supply are of vital importance for subsea processing. The purpose of this work has been to develop a small high voltage penetrator for use with high pressure vessels in the laboratory. Such equipment can facilitate high voltage and current testing of models ...
