New Motor Protection Standard IEEE 3004.8: Getting Up to Speed

IEEE Standard (STD) 3004.8-2016 IEEE Recommended Practice for Motor Protection in Industrial and Commercial Power Systems [1] is the first industrial-based standard providing detailed protection setting tables with companion single-line and three-line diagrams of recommended protection schemes for multifunction motor protection relays. Comprehensive motor protection information and diagrams are included for adjustable speed drive (ASD) applications. The content triples and deepens the information from its predecessor: IEEE Std 242-2001 (Buff Book), Chapter 10. Contributions were incorporated from end users, manufacturers, and consultants from across the world, capturing advancements in protection technologies, including field experiences. Updates include motor protection for hazardous (classified) locations. This article covers a brief standard overview and deep dives into material that is most applicable to the petrochemical industry.
