Electric power quality monitoring results in different facilities

This paper presents results of electric power quality monitoring studies performed in different industries and in universities. The monitoring was made with an Electric Power Quality Monitor developed at the University of Minho. The studies were performed in different installations: textile industries, a pharmaceutical industry, a hospital and two universities. Therefore, the results showed in this paper were obtained in different electrical installations. It is important to emphasize that, the results here presented are not intended to establish profiles for each type of electrical installation. The aim is rather to show several electric power problems that occur in these types of facilities, and also to present the functionalities of the Electric Power Quality Monitor developed at the University of Minho, working out of laboratory, in real electrical installations.Fundação para a Ciência e a Tecnologia (FCT
