17th TC-4 Workshop IWADC on ADC and DAC Modeling and TestingJuly 18th and 19th 2013   Barcelona 39This paper shows that the increasing complexity of new equip-ment for the power grid, mainly transmitted through process-es of additional software, is an important issue and needs to be quickly assimilated by the metrological controls to prevent the emergence of problems in the way of smart grid. This pa-per aims to describe all relevant aspects of this particular ex-perience revealed in Brazil, discussing the real scenario and its challenges opposites.Configuration SDMEE installed in Brazil  The Evolution of Electrical Energy Measurement in BrazilAna Maria Ribeiro Franco 100, Rosane Moreira Debatin10011PE171   Detection and characterization of amplitude defects using Spectral Kurtosis Jose Maria Sierra-Fernandez101, Juan José González de la Rosa101, José Carlos Palomares-Salas101, Agustín Agüera-Pérez101This paper describes a new procedure for analyze amplitude defects, based on Spectral Kurtosis (SK). It extracts the kurto-sis of each frequency component, related to the amplitude evolution. The proposed procedure allows the identification and characterization of frequencies which amplitudes are constant or change suddenly will be identified. An amplitude defect involves a step in the amplitude level, and that affect to frequencies around 50 Hz, which originally are not present, and could be detected by the SK. On the left graph is shown the defect introduced and on the right graph the SK result.12PQ037
