Buchholz Relay

Transformer outages have a considerable impact on the power grid. Certain phenomena contribute to insulation degradation during operation and generate dangerous gas and oil flow inside the tank. The Hitachi Energy Buchholz Relays are designed to monitor and rapidly react to internal gas accumulation and oil flow changes. The Buccholz Relays provide a prompt alarm or trip signal, allowing the operator to shutdown the transformer quickly and prevent further damage.
