HERRERA BASABE, Pablo Tomás  e  HERNANDEZ AREU, Orestes. Diagnosing of the eccentricity of the electric generator: an approach to the predictive maintenance. Universidad y Sociedad [online]. 2024, vol.16, n.2, pp. 94-103.  Epub 30-Abr-2024. ISSN 2218-3620.

The failure of an electrical machine is an inevitable process due to the thermal, mechanical, electrical and environmental stresses to which they are exposed throughout their useful life, however, with an adequate maintenance strategy, it is possible to avoid unforeseen failures and ensure that the machine fulfills its design functions, minimizing the risks of breakdown. The aim of this study is to evaluate a new variable of diagnostic state (VED) of the eccentricity of electric generator set in-service. As a result of the theoretical research carried out, it is determined that the fundamental component of the current through the neutral of the generator constitutes a variable that provides information on the degree of eccentricity of the asset, which can optimize the maintenance management process due to its easy handling and its high content of information on the condition of the rotating machine.
