MTBF for MiCOM relays

[Milica_Repac]

Hello everyone,

I've document that states MTBF (Mean Time Between Failure) for MiCOM products P20, P30 and P40 ranges, last updated in January 2012 (see attachment). Is there any newer version of this kind of document, from this or previous year? I'm particularly interested in MTBF for MiCOM relays: P437, P443, P545, P645, P633, P139, P741, P743, C434 and C264, but it needs to be from newer date than 2012.

Any information would be helpful.

Thank you in advance.

Hello,

Thank you @Anonymous user for your prompt response, but I really need document that states MTBF (Mean Time Between Failure) for listed MiCOM relays (P437, P443, P545, P645, P633, P139, P741, P743, C434 and C264). The document needs to be from newer date than 2012.

MTBF (Mean Time Between Failure) gives information about average time between two failures, while MTTF (Mean Time To Failure) gives information on average time to a first failure of the product (in this case MiCOM relays).

Hello,

We consider MTB and MTTF are equal.  Please check slide 2 of the presentation.

"In this reliability results, we have calculated the MTTF values of the MiCOM products and we are considering that the MTBF equal to the MTTF. Indeed, when a product is repaired in one of our certified repair centre by hardware replacement, this product is equivalent to a brand new product. "
