The Institute of Electrical and Electronics Engineers (IEEE) has published a new standard, IEEE Std. 3004.8-2016, “Recommended Practice for Motor Protection in Industrial and Commercial Power Systems.” The “color books” are in the process of being reviewed, updated and their designations changed. Each of the thirteen books in the “IEEE Color Book” standards series deals with a different aspect of electrical power production, distribution, and utilization in industrial and commercial power systems; 3004.8 supersedes Chapter 10 of the “Buff” book, IEEE 242-2001.  

Work began on this process with the formation of a working group in September 2012 and ended with final IEEE approval December 6, 2016. The working group consisted of the Chair Lorraine K. Padden of Houston and 14 other engineers from around the globe. Dozens of others were involved in providing input and balloting the final version for approval. EASA was represented on the working group, and the EASA technical support staff provided substantial input including a complete new section on DC motor protection. The document became available for purchase on May 23, 2017, on the www.ieee.org website.  

The document resulting from this painstaking process will provide guidance for motor protection for industrial and commercial applications. As motor service centers, the more we understand about the application and protection of motors in their applications, the better service we can offer to our customers.
