Partial discharge localization using time reversal: Application to gas insulated switchgear

Gas-insulated switchgear (GIS) are some of the most reliable and most expensive equipment that are nowadays used in power systems. Condition monitoring of the power system equipment can help operators detect defects like partial discharges (PDs) early, pre ...

Parametric study of the TF coil design for the European DEMO

Pierluigi Bruzzone, Kamil Sedlák, Rainer Wesche, Roberto Guarino

In addition to a reduced number of feeders, which would simplify their integration in the cryostat of the tokamak, the present study considers the possibility to reduce the voltage during safety discharge of the toroidal field (TF) coils. A lowered dischar ...

Effects of vegetation at a bar confluence on river hydrodynamics: The case study of the Arno River at Greve junction

Giulio Calvani

River bars often form at river confluences due to variation in flow discharges or in sediment transport capacity; once these bars are grown, they constitute favourable habitats for vegetation development. In this work, we analysed the effect of vegetation ...
