Abstract
It is noted that monitoring and diagnosis of transformers technical state is a mandatory requirement for Smart Grid technology implementation in industrial electrical networks. The main characteristics of transformers operating in the main production shops of the OJSC "Magnitogorsk Iron and Steel Works" (OJSC "MMK") are given. It is found that there is a tendency to aging of transformer facilities. Functions of diagnosis system are explained. The authors describe the configuration of the monitoring system introduced in power transformers of electrical networks and substations of the OJSC "MMK". They offer examples of trends, which make it possible to control test parameters on-line. The main benefits of the system implementation are listed. The research group set the task to develop engineering methods of multiparameter monitoring, which might make it possible to isolate and identify the defect by the complex of diagnostic properties.
