CEDASPES EE3-MA Buchholz Relay 230 KV

The CEDASPES Buchholz relay model EE3-MA is an essential safety element for oil-cooled power transformers up to 230 kV. It protects the transformer from internal short circuits and other faults that can lead to gas formation in the insulation oil. The device continuously monitors the amount of gas generated within the transformer, initiated by electrical discharges in the oil. Upon reaching certain gas volumes, the relay triggers a pre-alarm or main alarm function, which can be used for monitoring or directly shutting down the transformer. The EE3-MA model is designed for reliable operation under demanding operating conditions in high-voltage networks. It supports proactive maintenance and prevents major damage to expensive transformers. Order spare parts.
