1200 KV Compressed Gas-Insulated Test Loop Completion. Final Report

摘要

A 1200 kV Compressed Gas-Insulated Transmission System (CGIT) rated at 5000 amp buried with a 2175 kV BIL, 1800 kV switching impulse and 1100 kV, 60 Hz withstand voltage. In order to verify the 1200 kV CGIT design for long-term service, a program was initiated to manufacture components for a 1200 kV test loop. The loop would consist of the Westinghouse CGIT bus, a General Electric CT/PT system for in-line assembly with the bus and an Ohio Brass SF sub 6 insulated zinc oxide arrester for direct assembly to the bus. This report describes the design, manufacturing and testing of the various compressed gas-insulated transmission systems bus component for the test loop. (ERA citation 11:027294)
