DESCRIPTION
IEEE C37.20.2-1987
This standard covers metal-clad and station-type cubicle switchgear containing but not limited to such devices as power circuit breakers, other interrupting devices, switches, control, instrumentation and metering, and protective and regulating equipment. It includes, but is not specifically limited to, equipment for the control and protection of apparatus used for power generation, conversion, and transmission and distribution. This standard is concerned with enclosed, rather than open, switchgear assemblies rated above 1OOOV. It includes equipments that are part of primary and secondary unit substations. It does not include gas insulated substation equipments. In this standard metalclad switchgear shall be called MC switchgear and station type cubicle switchgear shall be called SC switchgear. Whenever the data covers both types of equipments, then they shall be called ME switchgear.New IEEE Standard - Superseded. This standard includes only the requirements for metal- clad and station-type cubicle switchgear. These requirements were previously a part of ANSI/IEEE C37.20-1969 (R 1981), IEEE Standard for Switchgear Assemblies including Metal-Enclosed Bus (1974 Consolidated Edition). Other types of equipment previously included in ANSI / IEEE C37.20-1969 (R 1981) will now be incorporated in separate publications.
