Acesso em:.https://repositorio.ufpa.br/handle/2011/2682This work aims to develop a data acquisition system of driving electric loads in the industrial process of automated network system based on virtual instrumentation, enabling the monitoring and analysis of disturbances related to steady state Power Quality(PQ), such as voltage variations, harmonic distortion and voltage unbalance, where the results can be viewed on a friendly and intuitive interface to the user and stored conveniently in a database. This system is a viable solution due to have low cost in its implementation and to be flexible for monitoring and analyzing parameters of PQ in industrial processes when compared with traditional instrumentation.porAcesso AbertoQualidade da energia elétricaProcessos industriaisInstrumentação virtualPower qualityIndustrial processesVirtual instrumentationDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::SISTEMAS ELETRICOS DE POTENCIA
