The analysis of the electrical machines operation, usually appeals to monitoring and diagnosis techniques, the operation faults involving electrical, mechanical and aero-dynamical parameters modification. The mechanical faults are due mainly to the unbalance of the rotating parts of the electrical machines and their analysis can be carried out using the vibration amplitude versus time and/or the vibration speed versus frequency characteristics. This paper presents a fault identification method, using a comparative analysis of the vibration speed determined by two identical equipments. The proposed method is suitable for instance in the case of several identical generators in hydroelectric plants, but, in the present paper the method was applied to a secure glass manufacturing production line.
