MESSKO® MSAFE® Buchholz Relay

Buchholz relay – protection system MSAFE® for transformers
More than 100 years of experience went into the design of the rugged MESSKO® MSAFE® Buchholz relay. It reliably protects fluid-filled transformers and reactors with an expansion tank. The MR standard ensures maximum operating safety: Every device is subjected to a helium leak test. MESSKO® MSAFE® features integrated solid-body floats as well as protective magnetic switches and test buttons separated from the oil. Remote testing is possible via compressed air line. A wide range of flanges and an additional gas removal device are available for the device. An offshore version is also available.
- Long service life thanks to high-quality materials
- High operating safety due to helium leak test for oil and gas tightness
- Protective magnetic switches to prevent false triggering
