3、dly limit the voltage surges on 48 Hz to 62 Hz power circuits ( 1000 V) by passing surge discharge current and automatically limiting the flow of system power current are addressed in this standard. This standard applies to devices for separate mounting and to devices supplied integrally with other

The tests demonstrate that an arrester is able to survive the rigors of reasonable environmental conditions and system phenomena while protecting equipment and/or the system from damaging overvoltages caused by lightning, switching, and other undesirable surges.

All rights reserved. viii Introduction This introduction is not part of IEEE Std C62.11-2012, IEEE Standard for Metal-Oxide Surge Arresters for AC Power Circuits (1 kV). Metal-oxide surge arresters (MOSAs) described in this
33、 standard represent the most predominant surge arrester technology applied on ac power systems above 1 kV. This standard presents minimum criteria for the testing of such surge arresters. Matters of application of this type of surge arrester are covered in IEEE Std C62.22.aTesting and application of
34、 older technology silicon carbide surge arresters are covered in IEEE Std C62.1 and ANSI C62.2, respectively. For testing and application of surge protective devices for use in low-voltage circuits (1 kV and below), other standards in the C62 series are available. IEEE Std C62.11-2012 contains the f
35、ollowing significant changes from IEEE Std C62.11-2005: Revision of subclause 8.2 Discharge-voltage characteristics test (formerly 8.3) to: (1) remove references to shunt-gapped arresters, (2) modify method of determining front-of-wave discharge voltage, and (3) add requirements for verifying that p
36、ublished arrester discharge voltages are not exceeded Removal of optional 5000 h test from subclause 8.7 Accelerated aging test of polymer-housed arresters with exposure to salt fog Revision of subclause 8.8 Contamination test to apply only to multi-unit station or intermediate class arresters Revis

39、 subclause 8.13 Revision of subclause 8.13.1 (formerly 8.13.2) Low-current long-duration test for distribution arresters to change the 18-discharge application from three groups of six to six groups of three, and to eliminate the subsequent heating of the sample and application of discharges 19 and
40、20 Addition of new Switching surge energy capability verification test as subclause 8.14 Addition of new Single impulse withstand capability test as Clause 15 Revision of subclause 8.16 Duty-cycle test (formerly 8.14) to remove point-on-wave timing of initiating surges for gapless arresters Revision
41、 of subclause 8.17 Temporary overvoltage (TOV) test (formerly subclause 8.15) to reduce the number of test samples from five to four, and to require one test per sample instead of five tests per sample at each of the selected time ranges Deletion of former subclauses 8.16 Pressure-relief test for st
42、ation and intermediate arresters, 8.17 Short-circuit test for porcelain-housed distribution arresters, and 8.18 Short-circuit test for polymer-housed distribution arresters Addition of short circuit test procedure of IEEE Std C62.11a-2008 as new subclause 8.18, to replace deleted former subclauses 8
