IEEE Standard for Metal-Enclosed Interrupter Switchgear
| Published By | Publication Date | Number of Pages |
| IEEE | 1987 | 48 |
New IEEE Standard – Inactive – Superseded. Metal-enclosed interrupter switchgear assemblies rated above 1000V containing but not limited to such devices as interrupter switches, selector switches, power fuses, control, instrumentation and metering, and protective equipment are covered. The concern is with equipment for the control and protection of apparatus used for distribution of electrical power, but the standard is not specifically limited to such equipment. Equipment that is part of primary and secondary unit substations is included. Gas-insulated substation equipment and switching devices mounted integrally within a transformer enclosure are not covered.
