PC37.105 - Standard for Qualifying Class 1E Protective Relays and Auxiliaries for Nuclear Power Generating Stations and Other Nuclear Facilities

Project Details

This standard covers qualification of Class 1E protective relays and auxiliaries to be used outside the primary containment in Nuclear Power Generating Stations and Other Nuclear Facilities . Protective relays and auxiliaries located inside the primary containment in a Nuclear Power Generating Stations and Other Nuclear Facilities present special conditions beyond the scope of this document.

Existing Standards	Superseded IEEE C37.105-1987 - IEEE Standard for Qualifying Class 1E Protective Relays and Auxiliaries for Nuclear Power Generating Stations This IEEE Standards product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.
	Active IEEE C37.105-2010 - IEEE Standard for Qualifying Class 1E Protective Relays and Auxiliaries for Nuclear Power Generating Stations Basic principles, requirements, and methods for qualifying Class 1E protective relays and auxiliaries in nuclear power generating stations including digital and analog devices, but excluding devices located inside the primary containment, are covered.
