C37.20.9a-2024
IEEE Standard for Metal-Enclosed Switchgear Rated 1 kV to 52 kV Incorporating Gas Insulating Systems Amendment 1: Clarification of Metal-Enclosed Gas-Insulated Switchgear (MEGIS) Types Covered, Refilling and Monitoring Requirements, and Production Test Requirements
Metal-enclosed switchgear assemblies incorporating gas insulating systems containing, but not limited to, such devices as interrupter switches; selector switches; fuses; circuit breakers; control, instrumentation, and metering devices; and protective equipment are covered in this standard. Equipment for the control and protection of apparatus used for distribution of electrical power is also included, but not specifically limited to, in this standard.
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
