Revision Standard - Superseded. This standard applies to metal-oxide surge arresters (MOSAs) designed to repeatedly 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. This standard applies to devices for separate mounting and to devices supplied integrally with other equipment. The tests demonstrate that an arrester can 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.

To provide improved procedures for the testing of metal-oxide arresters to better assure product quality and integrity. This will be accomplished by refining existing test procedures and adding new requirements that better demonstrate arrester capability. Where new test requirements more suitably or more comprehensively demonstrate the capability of arresters than do existing requirements, existing requirements may be eliminated.
