A New Protection Strategy for Electrical Distribution Systems

In this paper, the authors propose a new protection strategy for electrical Medium Voltage distribution networks, based on a distributed intelligence system composed of a central unit and of many local processing units. The distributed intelligence system can precisely identify and locate faults in suitably limited times. Each local processing unit is composed of a data acquisition system and a data analysis system. The first allows the accurate reconstruction of the fundamental using only 1.5 cycles of under fault transient electrical quantities. The second performs suitably precise on-line fault diagnosis based on the data provided by the data acquisition module. The data acquisition algo…

The influence of the tape-casting process parameters on the geometric characteristics of SiC tapes

Abstract The production process of the tape-casting technique applied to the production of porous ceramic membranes, suitable for the separation of different chemical species, has been explored, with emphasis on the influence of the operative parameters on the macrogeometric characteristics of the manufactured ceramic porous tapes. The effects of the slurry casting rate, the doctor blade height and the mean particle diameter have been studied and the results reported. The characterization analyses indicate the degree of reliability of this technique to produce planar SiC components and the importance of the particle size in enhancing the structural homogeneity. A study on the variance analy…
