IEEE C37.09 2000

Revision Standard – Active. Reaffirmed September 2007. This IEEE Standards product is part of the C37 family on Switchgear, Substations and Protective Relays. The testing procedures for all high-voltage circuit breakers that include all voltage ratings above 1000 V ac and comprise both indoor and outdoor types having the prefered ratings as listed in ANSI C37.06-1997 are covered. Typical circuit breakers covered by these standards have max-imum voltage ratings from 4.76 kV through 800 kV, and continuous current ratings of 600 A, 1200 A, 2000 A, and 3000 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 IEEE Std C37.013-1993.
