IEEE C37.122-1993 IEEE Standard for Gas-Insulated Substations

standard by IEEE, 11/30/1993

Full Description

Scope

This standard establishes ratings and requirements for planning, design, testing, installation, and operation of gasinsulated substations (GIS) for alternating-current applications for voltages from 72.5 to 800 kV. Typical installations are assemblies of specialized devices such as circuit breakers, switches, bushings, buses, instrumentation, and the gasinsulating system. It does not include certain items that may be directly connected to gas-insulated substations, such aspower transformers and protective relaying.

Purpose

Update and expand existing C37.122-1983. Separate standards and guides in two distinct documents.

Abstract

Revision Standard - Superseded.Guidance in the application of relays and relaying schemes for protection against stator ground faults on high-impedance grounded generators is provided.
