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®.
