Moisture is a leading cause of transformer aging and outages. By choosing our condition-based self-dehydrating breather type eSDB for your transformer, you do not need to worry about site inspections and silica gel replacement. Your transformer will be continuously secured from moisture intake and you can collect data online required for your transformer health management remotely.

The breather 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.
