IEEE C37.013a-2007 PDF
The amendment is to address the specific requirements relative to ac high-voltage generator circuit breakers intended for use with generators rated between 10 MVA and 100 MVA.
The 1997 edition of C37.013 failed to win approval as an ANSI standard because, although the Scope says that it covers “…all ac high-voltage generator circuit breakers…”, the requirements for small generator circuit breakers were not adequately addressed. It is the main purpose of this supplement to add specific requirements for smaller generator circuit breaker applications, focusing on generators rated in the 10 MVA to 100 MVA range.
Amendment Standard – Superseded. This amendment includes special requirements better suited for generator circuit breakers used to protect smaller generators rated between 10 MVA and 50 MVA and between 50 MVA and 100 MVA. It is important because the existing standards for typical distribution circuit breakers specifically exclude generator circuit breakers from the scope.
