Power Utility – Filtration Solutions lightweight, cordless SF6 Leak Pointer can detect SF6 leaks in seven different sensitivity levels with a response rate of one second. The SF6 Leak Pointer is easy to operate with one hand. Leakage data is clearly presented on an LED display.
Myth About SF6 Gas In Electrical Equipment· 3. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas-tight compartments, greatly minimising leakage.
