Although per-unit quantities have been used for many years by designers of rotating machinery, the base quantities were not standardized, and it was necessary to define them in each publication. A working group of the Rotating Machinery Committee was created to propose a set of standard definitions. In 1961, a proposed standard was published for trial use. A critical review of that proposed standard resulted in ANSI/IEEE Std 86-1975. Recently, systems analysts and some designers of rotating electrical machinery have found it useful to have a single generic model for all types of machines. Therefore, alternate per-unit definitions, using input voltamperes as base power for induction motors, have been included in this new revision, as well as an example of an induction generator. 517 $a86-1987 - IEEE Recommended Practice 517 $aIEEE Std 86-1987: IEEE Recommended Practice: Definitions of Basic Per-Unit Quantities for AC Rotating Machines 606 $aElectric generators$xAlternating current 606 $aElectric generators 606 $aElectric motors 615 0$aElectric generators$xAlternating current. 615 0$aElectric generators. 615 0$aElectric motors. 676 $a621.317 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a9910135157803321 996 $aIEEE Std 86-1987$92573325 997 $aUNINA
