Proposed IEEE Standard for Instrument Shunts

This proposal covers standards for shunts used in connection with direct-current indicating instruments and other measuring devices. It was sponsored by the IEEE Power Systems Instrumentation and Measurements Committee since there are no existing industry standards for this type of equipment. Included are definitions of shunt terminology, general physical requirements, and basic accuracy and performance criteria. While sizes and ratings are not included in IEEE Standards, it was deemed advisable to append some recommendations on current and millivolt ratings with certain basic size and installation requirements to serve as guides to both users and manufacturers.
