4. Uma abordagem baseada em modelo para integração e gerenciamento dos dados de sistemas de manutenção inteligente através do uso de técnicas de realidade mista
A manutenção industrial é um dos grandes desafios na área de automação e manufatura da indústria. Este desafio tem se apresentado, em âmbito nacional, pela adoção da prática ¿predizer e prevenir¿ ao invés de ¿falhar e consertar¿. Enquanto o Brasil caminha para uma mudança de paradigma de manutenção, o cenário internacional se volta para s

8. THE COST OF MAINTENANCE TRANSFER UNDER LOAD TAP OF THE TRANSFORMERS POWER OF EXTRA HIGH VOLTAGE THE ELETRONORTE / METODOLOGIA PARA REDUÇÃO DE CUSTOS NA MANUTENÇÃO DOS COMUTADORES DE TAP SOB CARGA DOS TRANSFORMADORES DE POTÊNCIA DE EXTRA ALTA TENSÃO DA ELETRONORTE
In this work a methodology for reduction of maintenance cost in the on-load tap changers (OLTC) of extra high voltage is proposed. The methodology is based on the use of Artificial Neural Networks (ANN) for the intelligent processing of input signals of the commutator. The neural nets adequately trained allow to create an information system and dedicated dia
