The descriptions of the standard transient recovery voltage (TRV) envelopes and ratings are changed in this amendment. This is applicable for ac high-voltage circuit breakers rated above 1000 V and on a symmetrical current basis. The capability limits of these circuit breakers are determined to a major degree by the TRV. The revised descriptions of TRV bring the TRV requirements in IEEE standards into harmony with the TRV requirements in IEC standards that apply to the same type and class of equipment. The TRV revisions addressed in this amendment to IEEE Std C37.09-1999 are described in amendment IEEE Std C37.04b-2008.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
C37.71-2001
IEEE Standard for Three-Phase Manually Operated Subsurface and Vault Load-Interrupting Switches for Alternating-Current Systems
Requirements are given for three-phase group operated subsurface and vault load-interrupting switchgear with maximum ratings of 600 A and 38 kV, and for utilizing separable insulated connectors. Definitions are given, and service conditions and ratings are discussed.Design tests, production tests, and construction requirements are included.
C37.72-1987
Standard for Manually-Operated Dead-Front Padmounted Switchgear with Load/Interrupting Switches and Separable Connectors for Alternating-Current Systems
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
