AN ENHANCED API 546

The standard American Petroleum Institute (API) 546 third edition was written by and for users, consultants, and manufacturers to provide a common performance standard for large synchronous machines. The standard is designed as a stand-alone document listing the requirements of all aspects of a synchronous machine. When compared with earlier editions, this edition has various enhancements designed to make it easier to purchase or specify a more durable machine. It has new requirements in some areas such as excitation systems, frame vibration, and insulation tests, as well as improved sections concerning dynamic analysis and thermally induced vibration changes. To reduce the risk of confusion, it should be used with the supplied data sheets.
