Revision Standard - Inactive-Reserved. The technical requirements for the design, fabrication, testing, and installation of a gasinsulated substations are covered. The parameters to be supplied by the purchaser are set, and the technical requirements for the design, fabrication, testing, and installation details to be furnished by the manufacturer are established.
This standard establishes ratings and requirements for planning, design, testing, installation, and operation of gas-insulated substations for alternating-current applications above 52 kV. Typical installations are assemblies of specialized devices such as circuit breakers, switches, bushings, buses, instrument transformers, cable terminations, instrumentation and controls, and the gas-insulating system. It does not include certain items that may be directly connected to gas-insulated substations, such as power transformers and protective relaying. This standard does not apply to gas-insulated transmission lines.
[The document will not include a purpose clause] The purpose of this standard is to address the special requirements, voltage ranges, and application practices of the North American Utility and Industrial market for high voltage gas-insulated substations, providing guidance for both users and manufacturers. Developed by a joint working group of The Substation and Switchgear Committees it brings together in one place the expertise from both groups and the information before covered in multiple locations into one document. This document also, where feasible, aligns with international norms and standards and recognizes international practices used outside North America. It will therefore provide a comprehensive standard with widespread application.
