IEEE C37.105-1987

IEEE Standard for Qualifying Class 1E Protective Relays and Auxiliaries for Nuclear Power Generating Stations

This IEEE Standards product is part of the C37 family on Switchgear, Substations and Protective Relays. The basic principles, requirements, and methods for qualifying Class 1E protective relays and auxiliaries, such as test and control switches, terminal blocks, and indicating lamps, for applications in nuclear power generating stations are described. The qualification procedure is generic in nature and can be used to demonstrate the design adequacy of such equipment under normal, abnormal, design-basis-event, and post-design-basis-event conditions. Protective relays and auxiliaries located inside primary containment areas in a nuclear power generating station are not covered.

Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.


No Active Standards

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No Superseded Standards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No Inactive-Withdrawn Standards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.
