Sensores de corrente elétrica no contexto das redes inteligentes (Smart Grids).

Abstract

Smart grids emerge as an innovation for the old existing electrical networks. This innovation brings many benefits to electric utilities, consumers and all businesses that create and manufacture the intelligent technologies. In this paper is presented an approach for smart grids, highlighting the benefits arising from it, the key technologies that need to be inserted in traditional electrical networks to make them smart, besides showing the deployment of this technology in Brazil and in the world. The emphasis of this work are the electrical current intelligent sensors. In this particular, are presented some types of these sensors, their operating principles, the most suitable materials used in its construction, such as amorphous alloys and nanocrystalline alloys and their applications in the electrical system. Prior are shown the main differences between conventional current sensors and smart sensors
