Long-term, operationally reliable and cost-efficient operation of a system even in the limit range:
With its intelligent sensors, MR offers the best and most practical monitoring of transformers. The field devices provide solutions for all aspects of the power transformer system. They ensure permanent and efficient operation, process the physical and chemical measured variables, make this data available and provide recommendations for action.
