Introduction This introduction is not part of IEEE Std C37.122-2010, IEEE Standard for High Voltage Gas-Insulated Substations Rated Above 52 kV . IEEE Std C37.122-1983 was i

3、nitiated in the early 1970s when the first gas-insulated substations were introduced. The reliability of gas-insulated substations has improved greatly since the first installation in the late 1960s. Utilities have taken advantage of the greater flexibility offered by gas-insulated substations to lo

4、cate substations closer to load centers with considerable savings in sub-transmission systems costs and reduced system losses. In addition, gas-insulated substations typically offer 25 to 30 years or more of operation before major overhaul is required. To address IEEE policy that IEEE standards shou

5、ld be harmonized with international standards whenever possible a study was conducted by a joint task force of the Substations Committee and IEC. This included a comparison of IEEE and IEC gas-insulated switchgear standards. The recommendations of that task force and joint working group were a serie

6、s of recommendations to modify both IEEE and IEC gas-insulated switchgear standards to move toward harmonization. This document is a step in that process.
