Hello Everyone,

Does anyone has a cheat sheet for quick reference for typical settings requirement for Protective relays. For 50/51 function coordination study is performed to obtain the settings. I am looking for a cheat sheet or a document for other typical protective functions like:

1. 25
2. 27
3. 46
4. 47
5. 59
6. 81
7. 87
8. 32
etc.

Typically IEEE color books will be refereed for these, I was just wondering if anyone has something handy atleast a list for which books to refer too.

How about the results from googling "ieee device numbers"?
 
Refer to IEEE C37.2 - Standard for Electrical Power System Device Function Numbers, Acronyms, and Contact Designations
 
MBrooke. is 96 not Ansi stnd for breaker fail?
 
ANSI code 95 through 99 are user-defined for use where the other codes don't cover the function. Not that I particularly agree with 50BF being a breaker fail - that one is a GE designation I think. The suffix letters are poorly defined in my opinion, for example 'G' is used for both Generator and Ground, sometimes on the same scheme.

 
Ah that makes sense. Thanks ScottyUK. yeah i noticed that too about GE and i think SEL also has a couple that are particular to them as well.
 
The ANSI standard does not define a standard usage for the suffices. Sometimes usage is in direct conflict. e.g. GE/Multilin vs SEL.
