This work addresses the predictive maintenance problem in operation centers of a transmission utility. Therefore, the primordial aspects are identified for the definition of a predictive inspection routine, which allows a check of points that guarantee periodic evaluations of the power system, so that the problems that occur can be detected in advance, allowing the maintenance crew to be activated before the occurrence of failures that actually affects the operation of the system. As part of the work, a survey was carried out with some Operation Centers of power system utilities in Brazil to give an idea of the application of maintenance and inspection concepts in the current national reality. Based on the results, it is shown to what extent the inspections adopted today in the Operational Centers of the various utilities have predictive characteristics, and an evaluation is made to identify if there are improvement points or not in this area. From the inspection philosophy proposed in this research, computational developments were carried out with the aim of developing a predictive inspection methodology to be adopted by the operators in a real time environment. The tool developed was applied at the Operation Center of the São Luís, using data from São Luís III Substation of Eletrobras Eletronorte and the results are discussed in order to highlight the advantages and disadvantages of the proposed tool and if it is able to meet the proposed objectives.
