The Future is Bright for Intelligent Transformers

Transformer fleets are getting older, energy networks are becoming more and more complex, and important know-how is being lost through demographic change. What can we do about it? The solution is to use intelligent equipment.

Through ETOS® – the Embedded Transformer Operating System – Reinhausen is providing an open, modular system solution for monitoring, controlling, regulating, and digitalizing power transformers. It is the world’s first open operating system for intelligent transformers.


One Solution for Everyone

The modular structure makes ETOS® a flexible solution for a wide range of digitalization projects and applications.


  “The gradual digitalization of our transformers enables us to evaluate the status of our systems significantly more quickly, more efficiently and, above all, more consistently than before. We now no longer need to travel to the transformers but can access them directly from the control center instead.”Rúnar Svavar Svavarsson, Technical Manager at Veitur, Iceland

The network operator

Dispersed generators, volatile voltages, increased network complexity, and loss of know-how are just some of the challenges facing network operators. ETOS® helps to increase the reliability and resilience of networks and enables more efficient utilization of transformers during operation and maintenance. During the duration of their projects – and at any time afterwards – network operators can benefit from Reinhausen’s advice and expertise.


“The new, open operating system for power transformers allows us to provide our customers with key advantages: We network our transformers with our customers’ digital environments, increase reliability, and maximize flexibility with regard to connecting components and accommodating the requirements of asset management.” Dr. Jan Declercq, CTO at SGB-SMIT Group

The transformer manufacturer

All of the experience gained by Reinhausen over decades of working with transformers has gone into ETOS® which provides transformer manufacturers with a scalable, slimline, individually adjustable digitalization solution. So they don’t need to spend time and money developing their own systems. And thanks to its innovative technical solutions, no additional costs arise. The collected data even helps manufacturers to optimize their transformers and adapt them more effectively to network conditions and customer requirements in the future.


“We are confident that ETOS® and PSIcontrol will allow us to link network management Information and equipment information in an intelligent manner. The close partnership between PSI and MR creates new opportunities for optimizing network management which, for example, can significantly reduce network interventions and enable better utilization of the networks.” Wolfgang Fischer, Business Division Manager at PSI Software AG

The service provider

Service providers who plan new systems for operators can score points with digital concepts. The mounting of ETOS® directly on the transformer allows the captured data to be transferred to the control system via a standardized control-system protocol using a fiber-optic cable. This greatly reduces the amount of wiring needed compared to a conventional connection method. Furthermore, the open system allows service providers to integrate their own software in order to adapt processes to customer requirements.
