C37.09 - IEEE Draft Standard Test Procedures for AC High-Voltage Circuit Breakers with Rated Maximum Voltage above 1000V

The testing procedures for all high-voltage circuit breakers that include voltage ratings above 1000 V ac and comprise both indoor and outdoor types having the preferred ratings as listed in IEEE Std C37.04 are covered. Typical circuit breakers covered by these standards have maximum voltage ratings from 4.76 kV through 800 kV, and continuous current ratings of 600 A through 5000 A associated with the various maximum voltage ratings. The test procedures verify all assigned ratings, including continuous current, dielectric withstand voltages, short-circuit current, transient recovery voltage, and capacitor switching, plus associated capabilities such as mechanical endurance, load current, and out-of-phase switching. Production test procedures are also included. This standard does not cover generator circuit breakers as these are covered in IEC/IEEE Std 62271-37-013.
