Worldwide demand for new T&D networks will increase in the near future pushing the utilities to install a larger number of high voltage equipment like cable terminations, bushings and surge arresters. Meanwhile the attention to environmental and safety issues is generally increasing . The aim of this paper is to analyze the potential risks associated […]
Medgrid is a European industrial initiative to study the feasibility of a 1,000 MW HVDC transmission project connecting North Africa to Europe. Medgrid assigned to a Consortium led by CESI (together with Intertek and Parson Brinckerhoff) a feasibility study aimed at providing answers to technology and cable limits, laying methods, maintenance, costs and planning, for […]
InGaP /InGaAs/Ge triple junction solar cells with a size of 26.5 cm2, thickness of 120+/- 20 μm and AM0 efficiency class 30% (CTJ30%), have been manufactured and qualified following the ESA ECSS E ST20-08 standard. These solar cells have been developed on a large MOCVD epitaxial reactor, VEECO E450G, suitable to simultaneously process up to […]
This paper reports the results of a hydrodynamic study developed by an unsteady monodimensional numerical model, supporting the management of Tevere river floods in use by Enel at Nazzano barrage since the 1960s. The model compares the effects of Enel operational criteria with the results obtained by applying the principles indicated by National Technical Services […]
This paper contains the results of the back analysis performed after the earthquake of April 2009 (L’Aquila Central Italy) on the Rio Fucino gravity dam (reservoir of Campotosto, L’Aquila).The elaboration of the back analysis made it possible to estimate the shear strength at the contact surface between the dam and the rock foundation and the […]
Referring to the management of artificial basins, the reservoir sedimentation caused by erosion process and the consequent sediment transport and deposit in the basin is a fundamental aspect to be considered. The filling, or partial filling, with silt of a reservoir that receives fine-grained sediment brought in by streams and surface runoff leads to a […]
