Liquids like mineral and silicone oils insulate and cool a transformer. You need to monitor the level of the oil to assure reliable and safe operation of the transformer.

Choose our liquid level indicator type eOLI, an evolution of our conventional liquid level indicators, and continuously monitor from the remote any unexpected or accidental oil leakages that may lead to a transformer failure. The operator can monitor the preset values remotely or visualize the values on-site at men-height through the easy-to-read eViewer dial installed on the transformer wall and decide on the best transformer maintenance schedule.

The indicator is equipped with a digital interface for easy connection to smart grid applications and can be integrated into a system through a central control unit.  It is 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.
