IEEE C37.100: Standard Definitions for Power Switchgear
DOD Adopted ANSI Approved Approved
(This foreword is not a part of IEEE Std C37.100-1992, IEEE Standard Definitions for Power Switchgear.)
This standard continues the compilation of terms and definitions relating to power switchgear and should be considered to reflect common and current usage of that industry. It is an update of the 1981 revision with additions and changes.
The 1981 revision of this standard incorporated the definitions formerly contained in IEEE C37.90-1978, IEEE Standard for Relays and Relay Systems Associated with Electric Power Apparatus (ANSI). The agreement to move these definitions from IEEE C37.90-1978 to IEEE C37.100-1981 was based on identifying the definitions for prime responsibility. Accordingly, the code shown was adopted and is used in the current edition as well. Each of the eight participating entities of the Power System Relaying, Substations, and Switchgear Committees of the Technical Operations Department of the IEEE Power Engineering Society identified definitions in which they had basic responsibility. This is shown immediately following the definition. The code indicates interest and consent required for any changes.
The size of this standard has been kept to a minimum by omitting all terms satisfactorily covered in readily available dictionaries. In many instances, terms and definitions of related products exhibiting minor variations have been combined for greater clarity.
International Electrotechnical Commission (IEC) definitions have been adopted wherever possible, without change, or with minor modifications.
Specifications and ratings have been excluded from definitions where possible. This information is included in standards covering the specific products.
The terms and definitions in the standard are intended to encompass the products within the scope of the C37 project that include power switchgear for switching, interrupting, metering, protection, and regulating purposes as used primarily in connection with generation, transmission, distribution, and conversion of electric power.
The definitions of terms and explanatory notes relating thereto contained in this standard are not intended to embrace all possible meanings of the terms. They are intended for the sole purpose of establishing only those meanings of terms used in switchgear standards. They do not purport to embrace other meanings that the terms may properly have when used in connection with other subjects.
In some instances, terms and definitions that are not identical to those in this standard have been developed by other branches of industry. Where this situation exists, the definitions in this standard shall be used for power switchgear within the C37 product scope.
