IEEE PC37.82

Revision Standard - Active - Draft.
The methods and requirements for qualifying switchgear assemblies for indoor areas outside of the containment in nuclear power generating stations are described in this document. These assemblies include: metal-enclosed low-voltage power circuit breaker switchgear assemblies, as defined in IEEE Std C37.20.1™; metal-clad switchgear assemblies, as defined in IEEE Std C37.20.2™; metal-enclosed bus, as defined in IEEE Std C37.23™; and metal-enclosed interrupter switchgear assemblies, as defined in IEEE Std C37.20.3™.

This document describes the methods and requirements for qualifying switchgear assemblies for indoor areas outside of the containment in nuclear power generating stations. These assemblies include the following: a) Metal-enclosed low-voltage power circuit breaker switchgear assemblies, as defined in IEEE Std C37.20.1; b) Metal-clad switchgear assemblies, as defined in IEEE Std C37.20.2; b) Metal-enclosed bus, as defined in IEEE Std C37.23; c) Metal-enclosed interrupter switchgear assemblies (1 kV to 38 kV), as defined in IEEE Std C37.20.3
The purpose of this document is to provide amplification of the general requirements of IEC/IEEE 60780-323 as they apply to the specific features of Class 1E switchgear and metal-enclosed bus assemblies. Where differences exist between this document and IEC/IEEE 60780-323, this document takes precedence insofar as switchgear and metal-enclosed bus assemblies are concerned.
