IEEE C37.100.1-2007

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. Application of this standard shall be indicated by normative reference to IEEE Std C37.100.1-2007 in the relevant equipment standard on a section or clause-by-clause basis. Refer to Annex A. 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.1 In case of a conflict in requirements, the requirements of the relevant equipment standard shall prevail.

In conformity with the IEC style of IEC 62271-1, this document will not have a "Purpose" clause. However, the purpose of the document is best expressed in the following material contained in the "Foreword": This is a new standard written specifically to collect into one document the requirements that are common in many IEEE Power Switchgear Standards. It follows the concept already in place in IEC 62271-1. The expected benefits of this concept is to reduce the minor inconsistencies among the various switchgear standards and, where differences must remain, to have them highlighted by exception to these common requirements. It is the intention of the IEEE Switchgear Committee that the relevant [switchgear] standards will adopt the provisions of this standard by normative reference. Specific clauses may be adopted (a) without exception (the default), (b) with exceptions, (c) with additional requirements or a combination of (b) and (c), as deemed appropriate to the relevant standard. Refer to informative annex A for specific recommendations for use with a relevant standard. Note: IEC TC17 SC17A MT34 is currently developing IEC 62271-1. When the IEC 62271-1 standard is issued, it will replace IEC 60694. In an effort to promote harmonization, this standard is formatted similar to the IEC Standard.

New IEEE Standard - Superseded. This Standard collects the common requirements that are in many IEEE Power Switchgear Standards. These include: Service Conditions, Design (type) Tests, Design and Construction, Production (routine) Tests and Ratings. This standard applies to alternating current 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.
