Characteristics of SF6-filled Equipment
1. Introduced in the mid 60s
2. Continuous improvement make them still state-of-art (GIS)
3. Reduced space 1/7 of conventional air insulated substations (AIS)
SF6 Academy ~ Thomas Wortelmann ~ 12th May 2010
4. Extended life time (approx. 30-40 years)
5. Very reliable equipment
6. ............
but
little Experience when End of Life Time is reached !
