IEEE Standard Test Procedure for AC High-Voltage Circuit Breakers Rated on a Symmetrical Current Basis -- Amendment 2: To Change the Description of Transient Recovery Voltage for Harmonization with IEC 62271-100
Summary
Amendment Standard - Superseded.
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.
This revision harmonizes the IEEE requirements for transient recovery
voltage during power tests with those in IEC 62271-100. This is a
continuation of an effort to harmonize requirements in the IEEE standards
with those of IEC that first began in the 1950s. Broadly speaking, the
functional requirements to be demonstrated in power testing are changed only
slightly, whereas the manner in which the requirements are represented
graphically is simplified considerably.
