siemens.com/energy Turning energy into progress With traction transformers from Siemens Answers for energy.
The right choice worldwide Traction transformers for every application Siemens traction transformers are setting standards of quality and versatility around the world. Over a century of experience in development, construction and servicing has made Siemens one of the world s leading providers, and provides a solid foundation for customized, state-of-the-art railway transformers. Our cutting-edge methods and optimally trained employees at our four manufacturing locations guarantee out transformer quality worldwide. In a class of their own Siemens develops and manufactures traction transformers of all capacity ranges for rail-based vehicles. The long product life means that the focus is on maximum reliability, economic efficiency and safety and ensuring that the transformers are perfectly in line with the customer s requirements. This is reflected in different versions based on the following parameters: Frequency, capacity and voltage Dimensions, weight and place of installation Dissipation and short-circuit voltages Driving patterns and medium-frequency performance, and Environmental requirements (e.g. ester coolant). Proven technology Ultra-modern traction transformers from Siemens are found in locomotives using the Vectron platform as well as Amtrak. For multi-unit trains used in long-distance rail transport, traction transformers are used in the Velaro in the UK, China, Russia and Turkey, for instance, and in regional transport they make up the most advanced platform solution for railcars in the Desiro class. Siemens manufactures the traction transformers in its lead factory in Nuremberg and in production lines in Jinan, China; Mumbai, India; and Voronezh, Russia. This also enables local content requirements to be satisfied. Siemens traction transformers are manufactured worldwide by skilled professionals in accordance with the same high quality standards. 2 Vehicle connection to suit customer requirements Low-voltage versions for multi-system locomotives
Siemens has not only been awarded Q-1 supplier status for DB AG, but also holds the following certifications: DIN EN ISO 9001 DIN EN ISO 14001 OHSAS 18001 EN 15085-2 CL 1 GOST IRIS Comprehensive range of services From a technical perspective, Siemens traction transformers cover every preference. In all capacity ranges up to 10 MVA, and above, Siemens offers single-phase transformers for machine rooms, underfloor and low-floor construction, and for fitting in roof structures thus allowing plenty of freedom of design. The cooling plant can also be supplied to suit customer preferences, either integrated in the full frame or as a separate component, entirely in accordance with the engineers specific space requirements. Flexibility is also the order of the day when it comes to the selection of different cooling fluids. This means there are solutions for all capacity ranges that use oil or silicon, or the ester-based fluid that is particularly environmentally friendly. An internationally reliable partner New product developments come from the lead factory in Nuremberg, where close cooperation between Development and Production at the pre-production stage ensures that products are fully ready for manufacture. Uniform, IRIS-compliant quality standards are defined at the same time, which are binding for manufacturing at all production locations. A standardized, systematic structure for products, uniform machinery fleets and matching employee qualification standards at all manufacturing locations enable short delivery times and transport distances worldwide. Technical performance Frequencies from 16 ⅔ to 60 Hz Operating voltages: 1.5 kv DC, 3 kv DC, 15 kv, 25 kv, 11.5 kv or other special voltage levels Single or multi-system versions Integrated smoothing and filter chokes Auxiliary windings and heating windings, depending on customer specifications Traction windings as network filter chokes Refurbishment DC applications Low-noise pump with high power density Pfisterer plug connections 3
Global association makes for high performance Manufacturing and service for Siemens traction transformers Siemens traction transformers are in demand around the world reflecting the success of the international organization and the uniform quality standards across all four locations. Siemens not only satisfies the need for high-quality local value added, but by being close to its customers, it is able to respond faster to inquiries and spare parts orders and provide services directly on-site.

Testing traction transformers Routine tests Siemens traction transformers are tested essentially in the same way as power transformers to ensure maximum safety and reliability. Traction transformers often have a rated frequency of 16 ⅔ Hz, in addition to the more standard 50 Hz and 60 Hz. They also normally have one or more traction windings, windings for auxiliary voltages and heating windings. Choke coils or resistances may also be built into the tank. Routine testing of traction transformers includes the following: Measurement of winding resistances Measurement of ratios and proof of polarity Measurement of idling dissipation and idling current Measurement of relative short-circuit voltage, short-circuit dissipation and total dissipation Testing with applied power-frequency withstand voltage (testing of winding) Testing with induced power-frequency withstand voltage (testing of winding) Testing of step switch/tap changer (if present) Inductance measurement on a case-by-case basis Type evaluations Depending on customer requirements, type evaluations may examine different transformer properties. These are normally 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. Differing oil temperatures and also the coolant temperatures (i.e. air/water) are recorded in the process. The winding temperature is determined indirectly based on winding resistance, which is measured after the feed-in has been terminated. Pressure and throughflow measurements within the cooling circuit can also be agreed upon. In the case of transformers that are fed directly from the overhead lines, the high-voltage winding is subjected to a lightning impulse voltage test. Special tests Special tests on the traction transformers include the following: Measurement of magnetic field strength at different distances from the tank wall in three orthogonal directions Noise measurements Partial discharge measurement Mathematical proof of sudden short-circuit resistance. At the customer s request, a test may also be performed in an accredited third-party laboratory.
