Transformer outages have a considerable economic impact on the operation of a power supply network. Internal gas accumulation and oil flow are monitored and kept under control by the Buchholz relay.
Our gas detector Buchholz relays are designed to promptly provide information about internal malfunctioning, giving the possibility to shutdown the transformer and prevent its possible destruction.
Why Hitachi Energy?
- More than 50 years of experience in manufacturing transformer components
- The new generation of Buchholz relays with analog and digital output (eDevices)
- Global after-sales and customer support network
