IEEE C37.09-1999/Cor 1-2007

This corrigendum corrects technical and other non-editorial errors made during the preparation of C37.09-1999, which covers test procedures for all high-voltage circuit breakers rated over 1000 Vac . Editorial corrections have been made separately in an errata. The scope of C37.09-1999 is as follows:
"This test procedure summarizes the various tests that are made on ac high-voltage indoor and outdoor circuit breakers, except for generator circuit breakers, which are covered in IEEE Std C37.013-1997. It describes accepted methods used in making the tests and specifies the tests that will verify assigned ratings under ANSI/IEEE standards. This procedure does not preclude the use of other equivalent or more effective methods of demonstrating ratings.
The tests are divided into the following classifications:
a) Design tests (Referred to in IEC 60056-1987 and IEC 60694-1996 as Type Tests)
b) Production tests (Referred to in IEC 60056-1987 and IEC 60694-1996 as Routine Tests)
c) Tests after delivery
d) Conformance tests"

The purpose of this project is to correct errors introduced in C37.09-1999 between final balloting and publishing of the 1999 document. The 1999 document was created using manual methods, prior to the introduction of the modern electronic methods now in place in the IEEE Standards Association. C37.09 is a fundamental document to the testing of high-voltage circuit breakers, and therefore, the errors in the present document must be corrected prior to any general revision effort.

Corrigendum Standard - Superseded. Corrigendum to IEEE Std C37.09-1999. Reaffirmed September 2007. This corrigendum corrects technical and other non-editorial errors made during the preparation of IEEE Std. C37.09-1999 latest version, second printing 19 December 2005, which covers test procedure for all high-voltage circuit breakers rated over 1000 VAC. This text also includes corrections to the Errata dated 19 December, 2005, which adjusts Figure 17 on page 62 of the main text (under 7.2).
