Full Description

Purpose

This revision harmonizes the IEEE requirements for transient recoveryvoltage during power tests with those in IEC 62271-100. This is acontinuation of an effort to harmonize requirements in the IEEE standardswith those of IEC that first began in the 1950s. Broadly speaking, thefunctional requirements to be demonstrated in power testing are changed onlyslightly, whereas the manner in which the requirements are representedgraphically is simplified considerably.

Abstract

Amendment Standard - Active.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 circuitbreakers 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 inthis amendment to IEEE Std C37.09-1999 are described in amendment IEEE Std C37.04b-2008.
