Future Challenges for Cable Accessories in Medium Voltage Networks

In recent years, the architecture of the power system has been the subject of a major change. The commonly known structure with centralized generation and one directional power flow, gives gradually the place to the new concept of the power network where both the energy generators and consumers are distributed. Particularly, the continuously...

Original and pyrometamorphical altered Bentheimer sandstone: Petrophysical properties, surface and dielectric behavior

Bentheimer sandstone is a quartz-rich permeable hard sedimentary rock used for core flooding experiments. When fired to stabilize clays (subjected to high temperatures), pyrometamorphical phase changes induce texture and pore framework alteration. As a consequence the new dielectric response may influence wettability. The literature regarding...

Life-cycle assessment of high-voltage assets using statistical tool

Nowadays, utilities are confronted with assets reaching or even exceeding their designed life. This in turn, implies the occurrence of upcoming replacements to assure reliable network operation. In this thesis, the application of statistical tools for life-time and residual life assessment of high-voltage assets installed in a power network is...
