Winding temperature indicators

Winding temperature is a crucial parameter that should be monitored in large distribution transformers and power transformers. Accurate and stable measurement by maintenance-free thermometers provides insight into the overall performance of the transformer, while avoiding thermal degradation and ensuring a longer operating life.

ABB's winding temperature indicators are based on the Bourdon working principle, which eliminates maintenance, offers a wider temperature scale and produces no aging effects.
