IEEE C37.09a-2005 PDF

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 Amendment Standard - Superseded.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