IEEE PC37.04a

IEEE Draft Standard for Ratings and Requirements for AC High-Voltage Circuit Breakers with Rated Maximum Voltage Above 1000 V - Amendment 1

Summary

Amendment Standard - Active - Draft.


This amendment will address items discovered by users related to discrepancies with other industry standards: -Harmonize pollution levels for normal service condition. -Improve definition of low temperature requirements. -Further define requirements for capacitive switching class C0. -Clarify required electrical service capability. -Harmonize temperature limitations for contacts in non-oxidizing gases. -Improve definition of interrupting time. -Implement requirements from IEEE C37.11 which are more properly in C37.04. -Align material imported from NEMA SG-4 with current industry practices.
