IEEE PC37.06.1 to Address Ratings for High-Voltage Switchgear
September 8, 2009 // Published as a news service by IHS
The Institute of Electrical and Electronics Engineers (IEEE) will develop IEEE PC37.06.1 - Recommended Practice for Preferred Ratings for High-Voltage (>1000 Volts) AC Circuit Breakers Designated Definite Purpose for Fast Transient Recovery Voltage Rise Times.
IEEE PC37.06.1 is a revision to American National Standards Institute (ANSI) C37.06.1 - Guide for High-Voltage Circuit Breakers Rated on a Symmetrical Current Basis Designated Definite Purpose for Fast Transient Recovery Voltage Rise Times.
The rights to this standard were transferred from the National Electrical Manufacturers Association to IEEE in 2003.
This recommended practice will be used to supplement IEEE C37.06 - Standard AC High-Voltage Circuit Breakers Rated on a Symmetrical Current Basis - Preferred Ratings and Related Required Capabilities for Voltages above 1000 Volts for high-voltage circuit breaker applications where the transient recovery voltages rise to the crest value more rapidly than those specified in the earlier standard.
The IEEE also approved IEEE C37.04/Cor 1 - IEEE Standard Rating Structure for AC High-Voltage Circuit Breakers - Corrigendum 1.
