26、r Switches IEEE 1247, Standard for Interrupter Switches for Alternating Current, Rated above 1000 Volts This revision modifies the document title to allow for future inclusion of other types of High-Voltage Switches and to harmonize with the direction of the C37.30 series of standards. This revision
27、 includes the changing of the station, distribution and indoor voltage ratings of 8.25 kV, 15.0 kV and 25.8 kV to 8.3 kV, 15.5 kV and 27 kV respectively to harmonize voltage ratings between equipment classes. Station class voltage ratings of 121 kV, 169 kV and 242 kV have been changed to 123 kV, 170
28、 kV and 245 kV respectively to harmonize with AC High Voltage Circuit Breakers C37.06-2000 and IEC. Metrification of the document has continued by placing the metric equivalents first in the text and tables while retaining the inch - pound system in parentheses. Circuit switchers are excluded from t
29、his standard. The annexes are for information only and are not considered a part of the standard. Suggestions for the improvement of this standard will be welcome.
