Southern California Edison (SCE) energized the Rancho Vista gas insulated substation (GIS) on May 29, 2009. The substation uses a breaker-and-a-half scheme rated 63 kA at 550 kV and 80 kA at 245kV. The main buses at each voltage are rated 7,500 A continuous. The 500/230 kV substation was built to satisfy rapid load growth and increased reliability requirements for the northeastern Los Angeles Basin.

SF<sub>6</sub> gas has been widely used in high voltage power equipment (HVPE) because of its high insulating and arc-quenching performance. However, the reduction of use of SF<sub>6</sub> is highly required, because SF<sub>6</sub> is a potent greenhouse gas. Thus, the improvement of SF<sub>6</sub> gas insulation system is indispensable in order to further downsize HVPEs with reduced SF<sub>6</sub> usage. In this work, we applied a dielectric coating to 550 kV gas insulated switchgear (GIS) and succeeded in downsizing it and reducing its SF<sub>6</sub> gas content.
