Leakage current, arcing, flashovers, loss of insulating liquid, or excessively high flow rates can generate gas inside the transformer oil and affect the transformer performance.

Assure reliable and safe operation of the transformer and a power supply network.

Choose our Buchholz relay type eBR, an evolution of our conventional Buchholz relays. It continuously monitors gas accumulation and oil flow to the conservator from the remote. You will get a reliable product designed to discharge the accumulated gas and detect unexpected oil flow speed and avoid transformer shut down.

The Buchholz relay 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.
