During the month of January have been positive tested three traction transformers in the new SEA testing room for liquid immersed transformers.
The project is referred to a reconstruction of railway lines in the area of Beroun.
Our partners Power- Energo s.r.o. together with Representatives of Czech Railways (Prague) attended the Final Acceptance Tests in SEA testing room for the traction transformers, with Class V overload capability.
The main data of the transformers are the following:
Rated Power: 5300/2x2650 kVA
Rated Voltages: V1 = 23000 V (± 2 x 2,5 %) V2 = 2x1280 V
Vector Group: Yyn0d1
Cooling system: ONAN
These are the first transformers with secondary voltage 2x1280V that will be operated within the whole Czech Railways-Prague!
