Cause of SF6 emissions
Introduction
70 % of the SF6 emissions are caused
by inadequate gas handling!
Losses during SF6 handling
Technical recommendation acc. to CIGRE
“SF6 Handling Guide”
Regulations and guidelines
SF6 leaks of the plant
Determination acc. to IEC standards
Recommendation acc. to IEC
standard 62271-203 – max.
leak rate:
High voltage: 0.5 % p.a.
Medium voltage: 0.1 % p.a.

Residual gas emissions in SF6 recovery
Introduction
Old devices:
Residual SF6 gas at
50 mbar 0.304 g / l
1 m³ = 304 g
Residual SF6 gas at
20 mbar 0.120 g / l
1 m³ = 120 g
Residual SF6 gas at
5 mbar 0.030 g / l
1 m³ = 30 g
Stipulated final vacuum as per IEC 62271-4,
Chart 6, No. 4 for gas recovery: ≤ 20 mbar
Residual SF6 gas at
1 mbar 0.006 g / l
1 m³ = 6 g
