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.
ABB Buchholz relays are designed to promptly provide information about internal malfunctioning, giving the possibility to shut down the transformer and prevent its possible destruction.
