Description / Abstract:
This standard applies to alternating current (ac) switchgear, designed for indoor and/or outdoor installation and for operation at service frequencies up to and including 60 Hz on systems having rated voltages above 1000 V.
The technical requirements established in this standard serve as common reference to a number of equipment specific high voltage standards, either in its entirety or on a clause-by-clause basis as determined in those standards which cite C37.100.1.
NOTE 1—In general, this standard applies to all high-voltage power switchgear designed to IEEE C37™ series. Exceptions include low-voltage standards (1000 V and below) and protective relay standards.1
NOTE 2—For the use of this standard, “high voltage” (see IEV 601-01-27)2 is the rated voltage above 1 kV. However, the term “medium voltage” (see IEV 601-01-28) is commonly used for distribution systems with voltages above 1 kV and generally applied up to and including 52 kV.
NOTE 3—There are many common requirements found in the IEEE C37 switchgear standards. These include service conditions, ratings, and test methods. This standard is provided to promote standardization of the requirements and to simplify the maintenance of these standards.
