IEEE C37.71-2001

This project will be to review and revise the current ANSI/IEEE C37.71 to be consistent with other standards int his group and to include vault style switches. There is currently no standard for vault style switches. ANSI/IEEE C37.71 is typically followed for vault style switches, however there are operational and construction differences between vault and subsurface switches which need to be clarified. Revision Standard - Superseded. Requirements are given for three-phase group operated subsurface and vault load-interrupting switchgear with maximum ratings of 600 A and 38 kV, and for utilizing separable insulated connectors. Definitions are given, and service conditions and ratings are discussed.Design tests, production tests, and construction requirements are included.
