IEEE C37.09a:2005 (R2007)

IEEE Standard Test Procedure for AC High-Voltage Circuit Breakers Rated on a Symmetrical Current Basis- Amendment 1: Capacitance Current Switching

Summary

Amendment Standard - Superseded.
A revision to the capacitance current switching standards is included in this amendment.

The scope of PC37.09a is to incorporate IEC 62271-100 capacitance current switching treatment into the circuit breaker test code. This applies to Circuit Breakers above 1000V ac.
Capacitance current switching was not addressed in C37.09-1999 to take advantage of a joint IEC/IEEE working group on this subject. This Amendment will bring about harmonization with the new IEC 62271-100.
