Abstract
The experimental study of the energy behavior of an industrial user allows highlighting its energetic performance, the practical ways to improve the way in which power is used, as well as the validation of the theoretical hypotheses formulated in order to assess this user. The assessment of the power quality supplied in the public system and observing the quality indicators to fit in the standard permitted limits play an important role in order to establish the optimal functioning parameters for this industrial power user. In this paper, the results of the experimental study achieved at a large-scale/ industrial power user are exposed, along with the problems that emerged from this research. Moreover, solutions for solving these kind of problems are indicated
