The presence of electricity in various sectors of the economy allowed it to reach a level of importance, in which its rational consumption has become essential to maintain and increase its offer. This requires solutions (as mobile applications) that enable the costumer to know their instantaneous consumption and act on it. This paper presents methods for monitoring and controlling the energy consumption, which supported the development of an Android application (for mobile devices) to interact with a Smart Grid Network. It proposes methods for daily, weekly and monthly analysis, establishment of targets of energy consumption or targets of energy spending, and load control. The actual application are also presented along with its functional description. Through this application the costumer may visualize its energy consumption data and use this information to support decisions regarding the management, control or adequacy of their consumption habits. © 2013 IEEE.

This paper describes the characteristics of the Brazilian energy distribution market. A simulation of cost / impact due to a roll out of smart meters is preformed based on market values. The results show a significant increase in the rates to pay for the necessary investments. The paper also outlines a structure that enables the reduction of implementation costs by focusing of the expected benefits for the Brazilian reality. Source

This paper presents a solution for high voltage current transformers onsite errors verification, using a system composed by an optical current sensor as reference standard, suitable for live line installation up to 550 kV. The system is described; its performance results are presented, as well as field applications and results. Some limitations that have to be overcome to obtain a reasonable measurement uncertainty are also discussed. © 2011 IEEE. Source

The R&D Program of the Brazilian Electricity Sector has recently begun to encourage the newly developed technologies transference to market through R&D projects. However, the lack of adequate methodological references for project planning led the authors to propose a model to assist the energy utilities and research teams in the elaboration of R&D projects proposals for the electricity sector. In this context, this paper presents a case study of the Integrated Product Development Model Oriented for R&D Projects of the Brazilian Electricity Sector (MOR&D) application to elaborate a project of pioneer lot for a newly developed of a safety equipment with the incentives of the R&D Program, showing that, as in industry, a well-structured model may be the way to generate innovative projects and products, meeting completely the guidelines that all electric utilities are subject. © (2014) Trans Tech Publications, Switzerland.

This paper describes the development of an optical system for on-line thermal monitoring of power transformers immersed in oil using Fiber Bragg Gratings. The sensors were installed inside a power transformer near the high-voltage winding. The data obtained by the monitoring system were compared with data from conventional temperature sensor. Additionally the paper describes the attaching sensors technique employed and also the main difficulties encountered and the solutions adopted. Source
