Transformer Automation

CONTROL. REGULATE. MONITOR.

The growing number and greater average age of power transformers, and increasingly more demanding technical requirements on monitoring, control and regulation, are presenting growing challenges for the work of asset managers and grid management.

MR has over 20+ years of experience in automation and digitalization of transformers and gained valuable lessons from tens of thousands of projects around the world and listening to our customers helped us in prioritizing and making strategic portfolio decisions of our continuous ETOS® developments. At MR we believe in the value of standardization, of system integration and of transformer intelligence to increase reliability, to detect incipient faults, to assist with issue resolution and to increase flexibility and maximize the intake of renewable energy sources.

Intelligent and modular.

Our solution for the automation of power transformers is called ETOS® (Embedded Transformer Operating System) and is the world's first open operating system for intelligent transformers.

We offer a manufacturer-independent system for monitoring, controlling and regulating power transformers. Depending on the customer's requirements, the desired range of functions can be implemented on a modular basis - for different types, power classes and areas of transformer application.

ETOS® can be easily integrated or retrofitted in any environment. On one transformer or an entire fleet.
And best of all: This added value is absolutely system cost-neutral for you!
