This recommended practice applies to a Controllable Metal Oxide Arrester (CMOA) device designed to limit the switching overvoltage for 1 MV UHV AC systems. The recommended practice specifies the use conditions and overall technical characteristics of a CMOA device. Technical recommendations for the arrester body, controllable switch (including mechanical switch, power electronic switch, gap, and fast switch) and controller (controllable device) are described. Recommendations for test and inspection, marking, transportation, storage, material delivery, and operation and maintenance are also provided.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
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No Superseded Standards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No Inactive-Withdrawn Standards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.
No Inactive-Reserved Standards
