Comparative analysis for reactive energy measurement methodologies, under non-sinusoidal conditions in three-phase four-wire circuits
(2011-12-28)
This paper presents some methodologies for reactive energy measurement, considering three modern power theories that are suitable for three-phase four-wire non-sinusoidal and unbalanced circuits. The theories were applied ...
Planning of secondary distribution circuits through evolutionary algorithms
(2005-01-01)
In this work, the planning of secondary distribution circuits is approached as a mixed integer nonlinear programming problem (MINLP). In order to solve this problem, a dedicated evolutionary algorithm (EA) is proposed. ...

SAMAE: sistema automático de medição e análise de energia
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Eletrônica, 2012-10-19)
Electric energy consumers will soon have the option to choose the rate which best suits them, as this will be differentiated throughout a day and therefore they will be able to monitor their consumption as already happens ...
Electrical and optical characteristics of SnO2 thin films prepared by dip coating from aqueous colloidal suspensions
(1997-12-01)
Starting from aqueous colloidal suspensions, undoped and Nb5+ doped SnO2 thin films have been prepared by using the dip-coating sol gel process. X-ray diffraction results show that films are polycrystalline with crystallites ...
