Harmonization of ANSI/IEEE standards for high-voltage circuit breakers with IEC and its impact on application and analysis

摘要

ANSI/IEEE standards for high voltage circuit breakers have undergone changes in the recent years to harmonize with IEC standards. An example of such harmonization is the peak ratings, TRV (transient recovery voltage) profiles, classifications, voltage range factor. The paper compares these changes with the existing prevalent standards and practices and their impact on the applications and analyses.
