Comparison of international and NEMA standards for salient pole synchronous machines

The Electrical Machinery Committee (EMC) of the Power Engineering Society (PES) of the Institute of Electrical and Electronics Engineers (IEEE) has established a task force charged with the review and comparison of US Standards with international standards with a view to harmonizing these standards. This paper is in response to an assignment from that Task Force. It compares IEC 34 series of standards with National Electrical Manufacturers Association (NEMA) standards for salient pole synchronous machines for nonhydro applications.
