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 procedures 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). As of the printing of this corrigendum, IEEE Std C37.09-1999 includes all of the following: ¿ IEEE Std C37.09-1999 latest version, second printing 19 December 2005; ¿ Errata to IEEE Std C37.09-1999 (edited 18 April 2007), which corrects typographical and editorial errors to the standard (note that these alterations have been made to the most current electronic version of the standard which is available online¿http://shop.ieee.org/ieeestore/); ¿ IEEE Std C37.09a-2005, amendment to IEEE Std C37.09-1999, which adds additional content to the standard; and ¿ this corrigendum, IEEE Std C37.09-1999/Cor 1-2007, which makes technical corrections to both the original IEEE Std C37.09-1999 and the subsequently published errata.

This standard is applicable to ac circuit switchers designed for outdoor installation and for rated power frequencies of 50 Hz and 60 Hz and rated maximum voltages of 15.5 kV through 245 kV. It is applicable only to three-pole circuit switchers for use in three-phase systems. This standard is also applicable to the operating devices of circuit switchers and to their auxiliary equipment.

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.
