The testing process made by TRAMAG
– What you can rely on
Insights into the transformer and choke production of a leading specialist
TRAMAG has stood for high-quality, reliable winding goods for almost 100 years. That is why all our products are subjected to 100% routine testing either in our German or in our Czech plant before they leave the factory. But also the upstream manufacturing process is subject to several defined quality checks at all stages of the value chain.
TRAMAG quality guidelines
The tests are generally based on our guiding standard, DIN EN61558 for transformers and chokes in the low-voltage range. This specifies exactly which type and routine tests are prescribed for the respective winding material.
Process of the inspection
Our products are 100% tested!
Final inspection at TRAMAG
Quality assurance of transformers and chokes.
There are specific test schedules for transformers and chokes, based on the standard and the quality guidelines.
Piece test sequence of transformers and chokes
- Protective conductor test
- High-voltage test with withstand AC voltage
- Open circuit / transformation test (transformers)
- Inductance test with LCR measuring bridge (chokes)
- Resistance test (chokes)
- Dimensional test
- Visual inspection
