increase train efficiency and performance - handle highest ratings in a minimum of available space - serve local content demands for worldwide application - afford maximum reliability and flexibility.
With over a century of experience in transformer technology, Siemens is one of the world’s leading suppliers for customized, state-of-the-art railway transformers. The secret to Siemens stellar track record is a refined system of global logistics, internationally binding quality standards, highly trained skilled workers and specialization.
Siemens develops and produces traction transformers for rolling stock applications of all relevant ratings and voltage levels. The focus is on maximum reliability, economic efficiency and safety – and ensuring that the transformers are perfectly in line with the customer’s requirements.
Siemens Transformers offers the opportunity to track the transformers in operation. Operators can not only monitor but optimize transformer performance. Monitoring and data analysis are the important factors for digitalization of traction transformer for rollingstock applications.
A new generation of sensors monitors transformer health
A modular multisensory system continuously monitors the “health” status of the transformer and modifies operation behavior according to the results of an onboard optimization algorithm. The Siemens monitoring system leverages a new generation of sensors. These sensors transmit data to a local, remote or cloud-based control system. After data processing, the actors will – if necessary – receive commands for correcting the operation behavior.
Benefit from the performance data of other traction transformers
Economical and technical information of each traction transformer is updated online and collected to optimize all similar transformers in operation. Our real-time monitoring system optimizes cost of operation cost and maintenance intervals, increasing energy and economic efficiency.
Siemens traction transformers operates a worldwide manufacturing and service network to serve customers all over the world. Their more than 20 manufacturing sites worldwide adhere to European quality and sustainability standards – regardless of the manufacturing location.
The top 3 customer benefits of Siemens strong global presence
timely responses to inquiries,
short processing time on spare parts orders,
fast access to services directly on-site.
This ensures that customers can rely on Siemens traction transformer, components and services, anywhere, anytime.
Siemens traction transformers are setting standards of quality and versatility around the world. Close cooperations with international standards committees guarantee the compliance with the specific requirements and standards.
Siemens is a founding member of the IRIS Initiative, and consistently implements its requirements. Our railway components comply with all the relevant standards, for example: DIN, EN, IEC, IEEE, ISO, EAC / GOST and ANSI, as well as the current fire protection standard EN 45545. With our certified components, we actively support the worldwide vehicle approval process; hence our traction transformers comply with all relevant standards, for example:
Siemens traction transformers owe their excellent track record to a refined system of global logistics, internationally binding quality standards, highly trained skilled workers and specialization in five basic transformer specification profiles.
Siemens uses the most advanced and comprehensive routine tests, type evaluations and special tests for maximized product reliability and customer satisfaction. Siemens traction transformers are tested essentially in the same way as power transformers to ensure maximum safety and quality.
Type evaluations examine different transformer properties, normally these are measurements of heating and lightning impulse voltage testing. For measurement of heating, losses are fed in based on the preceding measurement and subsequent types of operation. In the process, differing oil temperatures and the coolant temperatures (i.e. air/water) are recorded. The winding temperature is determined indirectly based on winding resistance. It measured after the feed-in has been terminated. Pressure and throughflow measurements within the cooling circuit can also be subject of an evaluation. In transformers fed straight from the overhead lines, the high-voltage winding undergoes a lightning impulse voltage test.
