A comparison of ANSI and IEC standards for power station polyphase induction (asynchronous) motors

The Institute of Electrical and Electronics Engineers (IEEE) is encouraging the comparison of American and offshore standards and documentation of the comparison findings. At the 1994 IEEE Winter Power Meeting, the Electric Machinery Committee Working Group on Standards Comparison met on February 2, 1994, to assign specific documents for comparison. Task Forces were established for nine categories of electric machinery. The subject of this paper is the comparison of ANSI C50.41-1982, ''Polyphase Induction Motors for Power Stations,'' with the IEC 34 series standards covering ''Rotating Electrical Machines,'' which was performed under the auspices of the Large Asynchronous Machines Task Force. The paper is based on the comparison issued on August 4, 1994.
