Power Quality is a multidisciplinary systemic challenge. It involves huge data collection, many utility areas, and many other players outside the utility. Because it must connect massive amount of measured current and voltage data from various process levels to almost all utility corporate areas, allowing power conformity, energy availability and high service quality (achieving national and international...
The main objective of this article is to propose a methodology for prioritizing actions in predictive maintenance substation equipment, applied to Power Transformers, which are eventually responsible for the income revenue of energy companies (generation, transmission and distribution). This is a reflection on the failure analysis and risk management with optimal use of predictive maintenance, to...
This paper presents a prospective approach on how load curves can be typified using the NCEA (National Classification of the Economic Activities) instrument and also based on energy measurement campaigns commonly carried out. The proposed method intends to obtain load curves sufficiently robust, despite the available measurements may not have statistical significance. The proposed hypotesis tries...
