Comem eWTI

Winding temperature is a crucial parameter that should be monitored in large distribution transformers and power transformers. It provides insight into the overall performance of the transformer, while avoiding thermal degradation and ensuring a longer operating life.

Our maintenance-free Comem winding temperature indicators, with digital and analog output, help avoid critical rises in winding temperature by continuously monitoring the winding hot spot and enabling fans and cooling systems to be activated at the correct time.
