Procedimento para checagem intermediária de máquina de medir por coordenadas
(Universidade Federal de Santa MariaBrasilEngenharia de ProduçãoUFSMPrograma de Pós-Graduação em Engenharia de ProduçãoCentro de Tecnologia, 2021-03-04)
The low or no reliability of a measurement system (MS) can lead to occurrences that limit or even hinder the provision of services or the development of products. This problem is linked to factors such as inexistence or ...
An electronic device for increasing the accuracy of high-voltage measuring transformers
(IEEE, 2000)
A new electronic system to assist high-voltage measuring transformers is proposed. This system compensates the voltage drops in the series impedances, which are the main cause of error in this type of transformer. An ...
Location of single line-to-ground faults on distribution feeders using voltage measurements
(2006-12-01)
This paper proposes a dedicated algorithm for lation of single line-to-ground faults in distribution systems. The proposed algorithm uses voltage and current phasors measured at the substation level, voltage magnitudes ...
Design of a portable device for continuous 24h measurement of biological signals in large animals
(Sociedad Argentina de Bioingeniería, 2019-03)
The clinical interest in the measurement of pulse wave velocity (PWV), as an indirect index of arterial stiffness, has led to the development of new devices whose characteristics and limitations are currently being analyzed ...
