Full Description

Scope

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.

Purpose

There is currently no standard for vault style switches. 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.

Abstract

Revision Standard - Superseded."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 separableinsulated connectors. Definitions are given, and service conditions and ratings are discussed.Design tests, production tests, and construction requirements are included."
