Winding and liquid temperature are key health parameters in the transformer. You need to monitor and control the temperature variations to assure reliable and safe transformer operation.

Choose one of our liquid and winding temperature indicators type eOTI/eWTI, an evolution of our conventional temperature indicators, and continuously monitor the liquid & winding temperature. It will allow you to keep any unexpected temperature rise that may lead to a transformer failure under control. Our accessories fit all transformer designs. Personalize the value settings for alarms and switches to fit your specific needs. The operator can monitor the preset values remotely or check the values on-site through the easy-to-read dial and decide on the best transformer maintenance schedule.

The indicators are equipped with a digital interface for easy connection to smart grid applications and can be integrated into a system through a central control unit. They are compatible with our complete eDevice family, can be connected also to third-party devices, and be part of our modular monitoring ecosystem for transformer diagnostics – MeDICA.
