IEEE Standard Rating Structure for AC High-Voltage Circuit Breakers Rated on a Symmetrical Current Basis: Amendment 1 Capacitance Current Switching
Summary
Amendment Standard - Superseded.
This amendment specifies the capacitance current switching portion of the rating structure for all ac circuit breakers rated above 1000 V, including both outdoor and indoor types having preferred ratings listed in ANSI C37.06-2000. The rating structure establishes the basis for all assigned capacitance current ratings including overhead line switching, cable switching, capacitor bank switching, and back-to-back capacitor bank switching.
The scope of PC37.04a is to incorporate IEC 62271-100 capacitance current switching treatment into the circuit breaker rating structure. This applies to Circuit Breakers above 1000V ac.
Capacitance current switching was not addressed in C37.04-1999 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.
