IEEE Standard for Indoor AC Switches (1 kV - 38 kV) for Use in Metal-Enclosed Switchgear
Revision Standard - Superseded.
Indoor ac medium-voltage switches for use in enclosures for application in power circuits at voltages above 1 kV through 38 kV are covered.
These include stationary or drawout, manual or power operation, fused or unfused.
This standard covers indoor ac switches rated above 1 kV through 38 kV for use in metal-enclosed switchgear as follows:
The term ''indoor'' is intended to indicate that the enclosure provides a degree of protection to the switch and the enclosure may be suitable for indoor, outdoor, or other service conditions and complies with the requirements of switchgear assemblies as defined by IEEE C37.20.2-1999 or IEEE C37.20.3-2001.
This standard does not apply to subsurface load interrupting switches in IEEE Std C37.71-1984, switches intended for use in padmounted switchgear in ANSI C37.72-1987 and ANSI C37.73-1998, or to high-voltage air switches in ANSI C37.30-1997.
The purpose of this standard is to define the basic design and performance requirements for indoor medium voltage switches intended for use in Metal-Enclosed Switchgear covered in ANSI/IEEE C37.20.2 and C37.20.3.
This standard is based upon design criteria stated in ANSI/IEEE C37.30, definitions and requirements for high voltage air switches, insulators and bus supports, ANSI C37.32 Schedules for preferred ratings, manufacturing specifications, and applications guide for high voltage air switches, bus supports and switch accessories and ANSI/IEEE C37.34 and C37.39 test codes for high voltage air switches.
For other switches see references C37.30, C37.32, C37.34 and C37.39.
