Caracterización de la calidad de la energía de un sistema eléctrico industrial con cargas eléctricas variables no Lineales

In the present study, the characterization of the quality of the energy of an electrical system of an industry specialized in metalworking with non-linear variable electrical loads is carried out, for the identification of problems that affect the operation of the equipment. The study was based on the implementation of sequential steps based on the characteristics of the electrical system and the requirements of power quality standards. Measurements were made in the transformer of the common connection point and in the twelve distribution transformers of the plant with class A network analyzers. As a result of the study, problems of voltage variation and power factor were identified in all transformers, and it was shown that in 11 distribution transformers, there are non-conformities in relation to the limits of total distortion of current demand. It was possible to show that the individual harmonic of the fifth order current (negative sequence) predominated in six transformers, the individual harmonics of the seventh order current (positive sequence) predominated in five transformers, and the individual harmonics of the third order current (zero sequence).), were the most recurrent in a transformer.
