IEEE C37.98 2013 Edition, December 11, 2013 Seismic Qualification Testing of Protective Relays and Auxiliaries for Nuclear Facilities
More info
Description / Abstract:
This standard specifies test methods and conditions to be used
in the seismic qualification testing of protective relays and
auxiliaries such as test and control switches, terminal blocks, and
indicating lamps for use in nuclear facilities.
Purpose
The purpose of this standard is to establish test methods and conditions for determining the seismic capability and to demonstrate seismic qualification of protective relays and auxiliaries specified in IEEE Std C37.105™-2010. The prerequisites for the qualification testing are defined in IEEE Std C37.105™-2010. These test methods are divided into three main categories, as described in IEEE Std 344™-2004; fragility, proof, and generic testing. To define the specific conditions for seismic testing of protective relays, the following parameters shall be specified:
a) The settings and electrical inputs to the protective relay and auxiliaries, and other pertinent information as detailed in this standard required to define its condition during the test
b) The unintentional change in state, contact chatter, deviation in operating conditions, tolerances, or other change in performance of the relay that constitutes failure
c) The seismic levels (required response spectra) to be imposed during the test
This standard provides guidance to establish the test parameters listed above, determine seismic capacity, and to demonstrate the ability of protective relays and auxiliaries to perform their safety function during and/or after the specified seismic motion. In addition, this standard provides the requirements for documenting the necessary seismic qualification of protective relays and auxiliaries.
