Currently there are a large number of electronic billing meters already installed that do not have a function of recording quality of electricity, and also have a monitoring system and consumption management, being the ...

A poor quality power causes large losses to society. Thus it is used an equipment named power quality analyzers for magnitude measurement of these disturbances and determine the causes of these abnormality. The principal ...

This work consists in the development of a project to modernize the electrical energy metering and control system of UFRN's central campus. Currently the university has a system of measurement of electrical quantities, ...

This work presents a low cost architecture for development of synchronized phasor measurement units (PMU). The device is intended to be connected in the low voltage grid, which allows the monitoring of transmission and ...

An electric power consumption monitoring system for indoor sectors of costumers was developed to an ANEELR&D project. The system uses wireless sensor networks (WSN) placed at strategic points of the power grid and connected ...

The large number of mobile devices increased the interest in low-power designs. Tools that allow the evaluation of alternative implementations give the designer actionable information to create energy-efficient designs. ...

This paper deals with the internal resistance measurement methodologies of lead acid batteries, aiming to identify which method is most effective in daily use in preventive maintenance of battery banks. The theory of battery ...

Electrosurgery is a surgical technique that uses an electrosurgical device for cutting, drying (desiccation), and coagulation of organic tissue, thereby reducing the risk of bleeding. Electrosurgical device uses sparking ...

Electric energy is currently an input of fundamental importance for human beings, which is present in the simplest daily activities, from lighting an environment to the most complex activities of the modern era, such as ...

This work aims at modeling power consumption at the nodes of a Wireless Sensor Network (WSN). For doing so, a finite state machine was implemented by means of SystemC-AMS and Stateflow modeling and simulation tools. In ...
