Reliability meets automation
In addition to driving the tap-changer, ETOS® ED lets you evaluate and record all of the relevant operating data from your power transformer, such as monitoring the tap changer or evaluating transformer utilization. ETOS® ED helps with focused planning of operation and maintenance. The solid, proven housing protects both the motor-drive unit and the integrated monitoring system. Optional automation solutions such as voltage regulation and cooling system control can also be included in the ETOS® ED order and used as supplementary equipment for controlling the transformer.
Fitting ETOS® ED on the transformer directly transfers all relevant data to the control station via network protocol using a fiber-optic cable. This greatly reduces the amount of wiring needed during installation and significantly cuts costs compared to a conventional connection method. Integration of additional functions makes this added value available to you without even impacting system costs. We are happy to advise you and develop solutions with you that are tailored to your exact needs. Of course, we can even commission your systems on site on request.
Our system for automating power transformers comprises monitoring and safety equipment, (intelligent) sensors, field devices for control, regulation and monitoring, superordinate fleet monitoring, and all the accessories needed for attachment and communication. We provide solutions for all transformers from all manufacturers, regardless of age and location – for one single transformer or an entire fleet. The subcomponents are split into the process level, field level and control level.
Our solution for automating power transformers is called ETOS® (Embedded Transformer Operating System) and is the world's first open operating system for smart transformers.
Through this approach, we offer a manufacturer-independent system for monitoring, controlling and regulating power transformers. As a complete solution for digitalizing transformers in the field level area, ETOS® forms the interface between the process and the control level. Desired function scopes can be implemented using a modular approach tailored to customer needs – for various transformer types, performance classes and usage areas.
ETOS® can be integrated or retrofitted seamlessly into any environment, on one transformer or an entire fleet. And the best part is that this added value has absolutely no impact on system costs for you.
BENEFITS OF AUTOMATING POWER TRANSFORMERS
- Operating reliability through effective control and prevention of faults
- Cost optimization through condition-based maintenance and functional integration
- Standard of the future in terms of safety and regulatory requirements
We offer modular system solutions for different applications power rating classes and models of power transformers. Decades of experience in the fields of control and monitoring of power transformers included. Through ETOS® , we are providing a complete open system for automating power transformers for the first time. It comprises monitoring and protective devices, (intelligent) sensors, field devices for control, regulation and monitoring, superordinate fleet monitoring, and all attachment accessories for communication.
The special feature is the simple connection of components in ETOS® . This enables an individualized configuration. Likewise, a simple expansion or renewal of your existing power transformers is possible. In this way, you are able to control and monitor your transformers effectively – for maximum availability and security.
