This article describes the experiences in revising and updating a key IEEE Standard C37.2 - Standard for Electrical Power System Device Function Numbers, Acronyms, and Contact Designations. The article cites the historical evolution of this standard dating back to 1928. The wide utilization of modern, multifunction relays and many new functions made clear the need to update the 1996 version of this standard. In addition the interweaving of communication facilities into protection and control requirements had to be addressed from function and designation points of view. The article demonstrates the importance of the involvement of the members of the IEEE in standards and the need for continued input from these members to ensure relevance to present application needs, coherence, and compatibility with other industry standards and practices.
