IEEE - C37.100.1
Common Requirements for High-Voltage Power Switchgear Rated Above 1000 V
|Publication Date:||5 December 2018|
This standard applies to alternating current (ac) switchgear, designed for both indoor and outdoor installation and for operation at service frequencies up to and including 60 Hz on systems having voltages above 1000 V.
This standard is applied in relevant equipment standards by a normative reference to this standard, IEEE Std C37.100.1, on a section or clause-by-clause basis. Annex A of this standard provides recommendations for its application.
The inclusion of this standard as a normative reference shall not imply that all of the requirements contained herein apply as a default. In the absence of a normative reference, this standard shall be considered informative only. In case of a conflict in requirements, the requirements of the relevant equipment standard shall prevail.
NOTE 1- In general, this standard applies to all high-voltage power switchgear designed to IEEE C37™ series. Exceptions include low-voltage standards (less than 1000 V) 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, such as temperature rise limits, and test methods. This common requirements standard is provided to promote standardization of the requirements and to simplify the maintenance of these standards.
This document does not include a purpose statement.
