MESSKO^® MSafe^®

PRODUCT DESCRIPTION

MSAFE® - THE BUCHHOLZ RELAY FROM MESSKO

The MSafe® acts as a central protection system for liquid-filled transformers and reactors with oil conservator. Installed in the pipeline between tank and oil conservator, it reacts to faults which occur inside the transformer. Damages which are not visible can be detected early by the Buchholz relay.

Gases moving in the direction of the oil conservator or shock waves created by the rapid gas development trigger the signaling system of the Buchholz relay. The Buchholz relay also takes over the function of an oil level indicator when there is not enough oil in the conservator or when there is an oil leak.

AN OVERVIEW OF THE ADVANTAGES OF THE MSAFE®

The MSafe® Buchholz relay impresses with its robust construction in which more than 100 years of experience in measurement, regulation and safety technology have been invested. Top-quality materials, high manufacturing quality and the latest testing devices all guarantee the reliability of Messko’s Buchholz relay.

EXTRA FUNCTION RELIABILITY DUE TO THE USE OF SOLID-BODY FLOATS

In contrast to frequently used hollow floats, the solid-body floats used by the MSafe® cannot fill up with oil and lose their buoyancy. Messko has had long years of positive experience with this material using it for the MTO series oil level indicators.

HELIUM LEAK TEST AS GUARANTEE OF OIL AND GAS LEAK PROOFNESS

Before being delivered, every single Buchholz relay is checked for leak proofness in addition to a function test. For this test Messko uses helium at its state-of-the-art test stand. This helium leak test guarantees maximum oil and gas leak proofness.

TWO OR FOUR SWITCHING CONTACTS

If desired, the device can be equipped with normally closed, normally open and / or changeover contacts.

PROTECTED REED SWITCHES

The reed switches of the MSafe® are separated by immersion pipes from the oil. An oil ingress into the reed switch is therefore impossible. These switches are freely accessible from the terminalbox. Replacement is possible without any interference to the oil circulating system.

REMOTE TESTING POSSIBILITY

At any time the MSafe® can be triggered via a compressed air line to test its readyness of operation.

TOP-QUALITY, RELIABLE MATERIAL

95% of the mechanical components are made of stainless steel. An offshore-quality MSafe® is also available as an option.

5 YEAR WARRANTY

As with many Messko products, we also provide the Messko 5-year warranty on the new MSafe®.
